c program:Why this program is giving redeclaration error

Code:

main(){
display();
}
void display(){
printf("abc");
}

I don't know why the compiler lets you declare main() that way (without void or a return type). But I think your problem is that using display() before declaring it implicitly declares it. Then the later definition doesn't match that implicit declaration.

Because you didn't

Code:

#include <stdio.h>

void	display	(void);

main()
{
display();
}
void display()
{
printf("abc\n");
}

Hope this helps some.

Try always "int" with 'main'
closing 'main' with "return 0;"
