for(i=0;i<5;i++)
s+=a[i]; //sums every element
return s;
}
int main() {
int sum,a[]={1,7,4,9,6};
sum=sumArray(a); //calling the function
cout<<"Sum of array is : "<<sum; //printing sum to console
return 0;
}
OUTPUT :
Sum of array is : 27
Explanation:
In the above mentioned code, an array is declared and initialized at the same time. A variable sum of int type stores sum returned the function sumArray() and then it is printed to the console. In the function sumArray(), a variable s of data type int is initialized with value 0 and a loop is executed in which every element of the array is added. At last, s is returned.
