Writing an integer to a file with fputs()

Question

It\'s not possible to do something like fputs(4, fptOut); because fputs doesn\'t like integers. How can I work around this?

Doing fputs(\"4\", fpt

Answer 1

The provided answers are correct. However, if you're intent on using fputs, then you can convert your number to a string using sprintf first. Something like this:

#include 
#include 

int main(int argc, char **argv){  
  uint32_t counter = 4;
  char buffer[16] = {0}; 
  FILE * fptOut = 0;

  /* ... code to open your file goes here ... */

  sprintf(buffer, "%d", counter);
  fputs(buffer, fptOut);

  return 0;
}
