C Functions

#include <stdio.h>

int sum (int r, int s, int t);

int main()

z = sum (x,y,z) + 65;

int sum (int A, int B, int C)

int total; ; total is a local variable

total = A + B + C);

return total; ; return the sum

C Program

#include <stdio.h> int Func1(int x); int Func2(int x); int Func3(int x); int Func4(int x); int main() { int A = 3; int B = 5; int C; C = A + B; C = Func1(C); C = C + 1; return 2; } int Func1(int x) { return Func2(x) + 1; } int Func2(int x) { return Func3(x) + 1; } int Func3(int x) { return Func4(x) + 1; } int Func4(int x) { return x + 1; }
