# How to perform the arithmetic operations on arrays in C language?

CServer Side ProgrammingProgramming

An array is a group of related data items that are stored with single name.

For example, int student; //student is an array name that holds 30 collection of data items with a single variable name

## Operations of array

• Searching − It is used to find whether particular element is present or not

• Sorting − It helps in arranging the elements in an array either in ascending or descending order.

• Traversing − It processes every element in an array sequentially.

• Inserting − It helps in inserting the elements in an array.

• Deleting − It helps in deleting an element in an array.

The logic to perform all arithmetic operations in an array is as follows −

for(i = 0; i < size; i ++){
sub [i]= A[i] - B[i];
mul [i]= A[i] * B[i];
div [i] = A[i] / B[i];
mod [i] = A[i] % B[i];
}

## Program

Following is the C program for arithmetic operations on arrays −

Live Demo

#include<stdio.h>
int main(){
int size, i, A, B;
float div;
printf("enter array size:\n");
scanf("%d", &size);
printf("enter elements of 1st array:\n");
for(i = 0; i < size; i++){
scanf("%d", &A[i]);
}
printf("enter the elements of 2nd array:\n");
for(i = 0; i < size; i ++){
scanf("%d", &B[i]);
}
for(i = 0; i < size; i ++){
sub [i]= A[i] - B[i];
mul [i]= A[i] * B[i];
div [i] = A[i] / B[i];
mod [i] = A[i] % B[i];
}
printf("\n add\t sub\t Mul\t Div\t Mod\n");
printf("------------------------------------\n");
for(i = 0; i <size; i++){
printf("%d \t ", sub[i]);
printf("%d \t ", mul[i]);
printf("%.2f\t ", div[i]);
printf("%d \t ", mod[i]);
}
return 0;
}

## Output

When the above program is executed, it produces the following result −

Run 1:
enter array size:
2
enter elements of 1st array:
23
45
enter the elements of 2nd array:
67
89
------------------------------------
90    -44     1541  0.00    23
134    -44    4005  0.00    45
Run 2:
enter array size:
4
enter elements of 1st array:
89
