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 −
#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:\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 ++){
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("\n add\t sub\t Mul\t Div\t Mod\n");
printf("------------------------------------\n");
for(i = 0; i <size; i++){
printf("\n%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
