The C programming language made simple

Return value of a function

#include <stdio.h> #include <stdlib.h> #include <string.h> void fibo(int k) { int n1, n2, x; int i; n1 = 0; n2 = 1; for (i = 0; i < k - 2; i++) { x = n2; n2 = n1 + n2; n1 = x; } printf("The %dth number: %d\n", k, n2); return n2; } int main(int argc, char* argv[]) { int r = fibo(6); printf("We got %d in the main function\n", r); int r2 = fibo(17); printf("We got %d in the main function\n", r2); return 0; }
