Calculate Sum and Average of N Numbers using Arrays: C Program

https://technotip.com/8822/calculate-sum-and-average-of-n-numbers-using-arrays-c-program/

Lets write a C program to calculate Sum and Average of N numbers using Arrays and using macros and for loop.

Formula To Calculate Sum and Average int a[5] = {2, 4, 6, 5, 9};

sum = 2 + 4 + 6 + 5 + 9; average = sum / 5.0;

Typecasting int N = 5;

sum = 2 + 4 + 6 + 5 + 9; average = sum / (float)N;

Since N is integer type variable, dividing any number by N would give us integer data. For some input it’ll result in wrong result. To fix it, we make use of typecasting and cast the type of N to float using above syntax.
