Why would it want ( before return 0;?

The C programming language is everywhere, and learning it will help you become a better programmer ready for the next challenge in any field of computer science!


this doesn’t make sense does it?
what am I lacking?
#include <stdio.h>
#include <math.h>

int main(){
int a,b;
while(1<=a<=b<=101010){
printf(“%d”,30);
}
while(1<=a<=b<=10101010){
printf(“%d”,30);
}
while(1<=a<=b<=10
10101010){
printf(“%d”,20);
}
while(1<=a<=b<=10
1010101010){
printf(“%d”,20);
}
}
return 0;

}

I think you have an extra } before the return 0;
