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

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

For example, int student[30]; //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 ++){    add [i]= A[i] + B[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[50], B[50];    int add[10], sub[10], mul[10], mod[10];    float div[10];    printf("enter array size:
");    scanf("%d", &size);    printf("enter elements of 1st array:
");    for(i = 0; i < size; i++){       scanf("%d", &A[i]);    }    printf("enter the elements of 2nd array:
");    for(i = 0; i < size; i ++){       scanf("%d", &B[i]);    }    for(i = 0; i < size; i ++){       add [i]= A[i] + B[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("
 add\t sub\t Mul\t Div\t Mod
");    printf("------------------------------------
");    for(i = 0; i <size; i++){       printf("
%d\t ", add[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 add    sub     Mul    Div    Mod ------------------------------------ 90    -44     1541  0.00    23 134    -44    4005  0.00    45 Run 2: enter array size: 4 enter elements of 1st array: 89 23 12 56 enter the elements of 2nd array: 2 4 7 8 add  sub Mul  Div   Mod ------------------------------------ 91  87  178   44.00  1 27  19  92    5.00   3 19  5   84    1.00    5 64  48  448   7.00    0
