# C Program to calculate sum of N given numbers

Get input n and n inputs and calculate the sum of n inputs.

Sample Input 1:

4 6 5 3 2

Sample Output 1:

16(6+5+3+2)

#### Program or Solution

#include<stdio.h> int main() { int n,i,num,sum=0; printf("Enter number of numbers to sum:"); scanf("%d",&n); printf("Enter %d numbers to sum:"n); for(i=1;i<=n;i++) { scanf("%d",&num); sum=sum+num; } printf("The sum is:%d",sum); return 0; }

#### Program Explanation

Instruction(s) inside the for block{} are executed repeatedly till the second expression (i<=n) is true.

Here i is initialized to 1 and incremented by 1 for each iteration, instructions inside the **for** block are executed unless i becomes greater than n.

so value of num given by user will be added to sum at each iteration.

after adding all n numbers given by user to sum, sum will be printed using printf statement.
