types of array in c programming

In this article, today learn types of arrays in c programming one-dimensional array and two-dimensional array as we have seen some programs on a one-dimensional array now we will go for a two-dimensional array.

along with pointers in both arrays of one dimensional and two dimensional two dimensional array an array with two subscripts is called as two dimensional array it is nothing but a matrix which consists of rows and columns

1.one  dimensional array

2.two dimensional array

1.one  dimensional array:

One Dimensional (One-D) Array Programs / Examples - This section contains solved programs on One Dimensional Array, here you will learn about the declaration, initialization of the array and other basic and advanced operations on array like reading, printing array elements, sum and product of array elements, merging two arrays, adding and subtracting two arrays elements, swapping adjacent elements, sorting, searching, etc.

 Example:

#include<stdio.h>

#include<conio.h>

void main()

{

            clrscr();

            int arr[50], n;

            printf("How many element you want to store in the array ? ");

            scanf("%d",&n);

            printf("Enter %d element to store in the array : ",n);

            for(int i=0; i<n; i++)

            {

                        scanf("%d",&arr[i]);

            }

            printf("The Elements in the Array is : \n");

            for(i=0; i<n; i++)

            {

                        printf("%d  ",arr[i]);

            }

            getch();

}

1.    two  dimensional array:

 two dimensional array can be defined as an array which holds some more arrays in it usually it is in contiguous memory locations that we'll see in pointers and coming to seeing matrix which consists of rows and columns that is for our representation sake

 the syntax is the type again which is which can be integer float or character and the variable name of the array along with the row size and column size so if it is an only single set of brace it is one dimensional array but here as you can see two dimensional array is nothing but two set of sizes given for it and this is how we will initialize it an example offset is so we'll go for a slight initialization of this two dimensional array.

example:

 #include<stdio.h> 

int main(){     

int i=0,j=0;   

int arr[4][3]={{1,2,3},{2,3,4},{3,4,5},{4,5,6}};    

//traversing 2D array   

for(i=0;i<4;i++){   

 for(j=0;j<3;j++){   

   printf("arr[%d] [%d] = %d \n",i,j,arr[i][j]);   

 }//end of j   

}//end of i   

return 0; 

}   

 the main function normally west. array of limit 5 this is single-dimensional but if you say this is our two dimensional array and the initialization happens in this way over a brace now comes our saying two three four and five the five things are represented by this size and three C's internally we need to give three values.

 four five six seven eight nine now if I stick to three over here, it will be a three by three array will stick to four by three arrays so this is the ending brace ending race starting race values 33 our nth column is what I need row and column 4 are equal to 0 or less than 4 R + + + 4 columns equal to 0 columns less than 3 columns plus now say printf the value comma array of wrote and column value after this parental newline a character so that we can represent it in an array format when you execute it and he forgot about commas over here okay so this is how your array will be

 represented in a matrix format way so this is a perfect metric shape the scan the values in the array similarly like we are printing we need to scan it for Rho equal to 0 and Rho less than 4 Rho plus + and for column equal to 0 columns less than 3 columns plus say scan if person D comma have a son array of row and column that's it with this we can scan some values with the values B the values up in this way it's a 4 by 3 matrix as you can see so consider this is a RR with which we are scanning printf first array newline character and with this will scan for the new languor faster now similarly go for BRR of again 4 and 3 of size likewise CRR again of 4 and 3 off sighs so with this we can add a and B RS and place the addition in C so here I am receiving first array values likewise I'll print allows the user.

 for secondary values in which fur so R equal to 0 and R less than 4 R plus and likewise for column equal to 0 columns less than 3 and column plus now say scan if person D comma ampersand BR r of r and c with this will scan the second values now after this will clear the entire screen and then now it comes to printing of ARR likewise, we can go for printing a newline character after that for R equal to 0 R less than 4 R plus and 4 columns equal to 0 column less than 3 column plus plus and say a printf person D comma B are operating rows and columns and say Newland character format lecture presentation sake now finally in the CR at the array are less than 4 R + + + 4 column equal to 0 column less than 3 columns plus say crl of art and seat should take up the addition of errors earth and seat + B are ours are then suite column and print there itself dear dad values person D comma C are earth are and seats value and print a new line character.

 for the matrix of presentation sake so here thing goes is a loop renting enter first error for that and scan for first status as say from the user to print secondary else get the secondary contents and I'll clear the previous outputs and I'll print the first arraign matrix format after that to newline characters I'll go for printing the secondary in matrix format than three newline characters finally printing the addition of both first and second arrays which I can say addition is in this way for clear screen we should use hashing glue corner dot H now execute the program it is asking me to enter first error values let it be one all the time now its secondary let it be two all the time after that it will clear the entire previous outputs displaying.

 the first error in the second array now the addition is three so this way addition and subtraction are possible in two-dimensional array which is which we call as matrix addition and subtraction by using arrays now in match we know we have transfers of a matrix that is changing the rows and columns if you have an array which is of consider 3 by 2 size 3 by 2 size and will scan certain values for row and column saying for R equal to 0 R less than 3 and R plus plus likewise for column equal to 0 column less than 2 columns plus now say scan s person D comma ampersand array of row and column now printed for R equal to 0 R less than 3 R plus and for column equal to 0 column less than 2 column plus plus printf person D comma array of Rouen column after that printer newline character put them in a set of braces.

 now trending in will change the row and column row is zero and are less than three R + + + 4 column equal to 0 column less than 2 columns + + now while printing instead of saying array of ruin called a missile I'll  interchange them here it's row and here it's a column and sees what happens this time printf a new line character and off main and here we'll say one more newline character.

 now execute the program as you can see here it is expecting me to give out 3 4 5 6 so actually, it is 1 2 3 4 5 6 now it is 1 3 2 4 and 5 3 5 so this way we can interchange our rows and columns making it a transpose of a matrix character array as we are saying integer array all the time if we say a character is in 4 in front of it it is a character array and this is how we define character STR orbit and goodbye all so this is how you can even define a character array there is a separate chapter on character array where which is called as strings where we'll be seeing the programming concepts on strings but as of now we will take pointers in two-dimensional arrays integer array holds some ten values like going for single-dimensional  of certain values and lets I will be the one so that I can repeat the loop I less than five and I plus very deaf person D comma ampersand area of I array of I let it be zero the address happens to be and instead of saying area of zero if you say m % 0 will get the address the concept of addresses and pointers will see in greater detail when we enter into pointers.
