Just 2 days ago I was writing MUCH more complex programs. Now I can’t get a basic int variable to store input from the user. Wtf have I done wrong? It keeps saying Methuselah was 0 years old, no matter the input value.Code:#include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <string.h> #include <math.h> int main() { int age; puts("How old was Methusalah?"); scanf(&age); printf("Okay, so...Methusalah was %d years old.", age); return 0;
