Can't find the error in following code :- expected unqualified-id before try()

Question

#include<stdio.h>
#include<string.h>
void try(char s[])
{
    if(strlen(s)>5)
    {
        puts("Error\n");
    }
}
int main()
{
    char string[10];
    int T;
    scanf("%d",&T);
    while(T--)
    {
        scanf("%s",&string);
        try(string);
    }

    return 0;
}

Still can't find the error... try is a simple function and as always i am creating a func and calling it. compiler is giving error - (expected unqualified-id before 'try')

Answer 1

I suspect you are trying to compile your code as C++ rather than C. In C++, try is a reserved word (it is used in exception handling).

$ gcc test.c
$ g++ test.c
test.c:3:6: error: expected unqualified-id before 'try'

You can use -x to set the language explicitly (with either gcc or g++):

$ gcc -x c test.c
$ gcc -x c++ test.c
test.c:3:6: error: expected unqualified-id before 'try'
