Why am I getting an undeclared identifier error? I dont know what to do here everything I’m reading says this should work. I’m getting the error on line 11, the first jerk call.Code:#include <stdio.h> #include <stdlib.h> #include <math.h> #include <string.h> #include <ctype.h> int main() { printf("He calls me on the phone with nothing say\n"); printf("Not once, or twice, but three times a day\n"); jerk(); printf("He insulted my wife, my cat, my mother\n"); printf("He irritates and grates, like no other!\n"); jerk(); printf("He chuckles it off, his big belly a heavin'\n"); printf("But he wont be laughin when I get even!\n"); jerk(); return 0; } //This is the jerk fiunction jerk() { printf("Bill is a jerk\n"); }
