String comparison C - strcmp()

Question

I\'m trying to compare two strings, but I fail achieving that. Why?

#include 
#include 

int main(){
    float a = 1231.23123;
            


        

Answer 1

If you want a set number of digits to compare against in a string, use the precision specifier in sprintf - %.5f, and as others have pointed out, the number you've picked cannot be represented by a float, but can be represented by a double. i.e.

double a = 1231.23123;
char b[32];
sprintf(b, "%.5f",a);
