i am unable to compile my code due to GetInt function not recognized, i have tried all the solutions available, but none seems working for me... here is my code:
[EDIT: unrelated code removed]
// ask user for inputs
printf ("WHAT IS YOUR FIRST INTEGER: ");
int j = GetInt();
printf ("WHAT IS YOUR SECOND INTEGER: ");
int k = GetInt();
printf ("WHAT IS YOUR THIRD INTEGER: ");
int l = GetInt();
the response i get continually is : adder-1.c:11:13: error: implicit declaration of function 'GetInt' is invalid in C99 [-Werror,-Wimplicit-function-declaration] int j = GetInt();
kindly help
