6. Program to find the average of three numbers with input values as integer and output value (avg) as float
#include<stdio.h>#include<conio.h> // Linux user - Remove this int main() { int a, b, c; float avg; printf("Enter any three numbers "); scanf("%d %d %d", &a, &b, &c); avg = ( (float)a + (float)b + (float)c ) / 3; /* we have type casted integer to float as a, b, c, 3 all are integer type and
integer / integer gives the result integer. */
