C program to sum of all elements in an array; Through this tutorial, we will learn how to calculate sum of all elements in an array using standard method, function and recursion in c programs.
Programs to Sum of all Elements in an Array in C
To calculate sum of all elements in an array using standard method, function and recursion in c programs:
- C Program to Sum of all Elements in an Array using Standard Method
- C Program to Sum of all Elements in an Array using Function
- C Program to Sum of all Elements in an Array using Recursion
C Program to Sum of all Elements in an Array using Standard Method
#include <stdio.h>
int main()
{
int a[1000],i,n,sum=0;
printf("Enter size of the array : ");
scanf("%d",&n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d",&a[i]);
}
for(i=0; i<n; i++)
{
sum+=a[i];
}
printf("sum of array is : %d",sum);
return 0;
}
The output of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 1 2 3 4 5 sum of array is : 15
C Program to Sum of all Elements in an Array using Function
#include <stdio.h>
int sumofarray(int a[],int n)
{
int i,sum=0;
for(i=0; i<n; i++)
{
sum+=a[i];
}
return sum;
}
int main()
{
int a[1000],i,n,sum;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d",&a[i]);
}
sum=sumofarray(a,n);
printf("sum of array is :%d",sum);
}
The output of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 4 5 6 7 8 sum of array is :30
C Program to Sum of all Elements in an Array using Recursion
#include <stdio.h>
int sumofarray(int a[],int n,int i)
{
if(i<n)
return a[i]+sumofarray(a,n,++i);
return 0;
}
int main()
{
int a[1000],i,n,sum;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d", &a[i]);
}
sum=sumofarray(a,n,0);
printf("sum of array is :%d",sum);
}
The output of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 7 5 1 2 5 sum of array is :20
