Code:#include <stdio.h> main() { char name[10]; short age; printf("enter your age.\n"); scanf("%d",&age); fflush(stdin); printf("please enter your name.\n"); scanf("%[^\n]",name); if (strcmp(name, "bruce") == 1 && (age >13 || age <18)) printf("u are the chosen one"); else printf("u are nothing"); getchar(); }
the error is
`strcmp' undeclared (first use this function)
i'm new in c
You need to #include string.h . Also, if you are trying to check a range, you want to make sure it's greater than 13 AND less than 18.

Well, a couple of things.
1. To use string functions you need to #include<string.h>
2. The minimum C program is:
3. Your indentation sucks. Read How should I indent my code?Code:int main(void){ return 0; }
4. Read Why fflush(stdin) is wrong
5. Your scanf statement is broke.
Code:scanf(%9[^\n]s, name);//Leave space for null character.

Dude where is the string.h?
Probably the same place stdio.h is.

Everytime you post, an angel dies.....anything with a floating point is automatically a double foe the computer. here you say 3.14f, it means.. oh wait, it's not double, it is float. use it as a float!

Code:#include <stdio.h> #include <string.h> <--- needed for strcmp() int main( void ) <--- not main() { char name[10]; short age; printf("enter your age.\n"); scanf("%d",&age); fflush(stdin); <----- remove this! printf("please enter your name.\n"); scanf("%[^\n]",name); if (strcmp(name, "bruce") == 0 && (age >13 && age <18)) <--- strcmp() returns 0 when match is found printf("u are the chosen one"); <--- || is incorrect for range checking else printf("u are nothing"); <---- learn to spell getchar(); return 0; <--- main returns an errorlevel to the Operating System }
