For two vectors a and b having n elements each, the addition operation yields a vector (say c) of size n. The ith element of the result vector is obtained by adding the corresponding vector elements, i.e., c_{i} =a_{i}+ b_{i}. The algorithm to perform the desired addition is given below.
Read n, the number of elements in given vectors
Read vector a
Read vector b
Perform vector addition c = a + b
Print result vector c
The program given below implements this algorithm in a straight-forward way using a separate for loop for the vector operation.
/* Vector addition */
#include<stdio.h>
int main()
{
int a[10], b[10]; /* vectors to be added */
int c[10]; /* result vector */
int n, i;
clrscr();
/* read vectors a and b */
printf("Enter vector size: ");
scanf("%d", &n);
printf("Enter elements of vector a:\n");
for (i = 0; i < n; i++)
scanf("%d", &a[i]);
printf("Enter elements of vector b:\n");
for (i = 0; i < n; i++)
scanf("%d", &b[i]);
/* perform vector addition */
for (i = 0; i < n; i++)
c[i] = a[i] + b[i];
/* print addition vector C */
printf("Addition vector:\n");
for (i = 0; i < n; i++)
printf("%d ", c[i]);
getch();
}
