Question

How can a number be converted to a string in C, explain with example.

Answer 1

The function takes a pointer to an array of char elements that need to be converted, and a format string needs to be written in a buffer as a string

int sprintf(char *str, const char *format, ...)

 

#include<stdio.h>

#include <math.h>

int main()

{

char str[80];

sprintf(str, "The value of PI = %f", M_PI);

puts(str);

return 0;

}

The output after running the above code:

Output: Value of Pi = 3.141593
