C++ (Cpp) convert_to_f Examples

Example #1

File: Ex5-1.c Project: gotoc/Practical-C_Programming_Exercises

int main(int argc, char *argv[])
{
  char line[100];
  float temp;
  
  do {
    printf("Enter tempertature: ");
    fgets(line, sizeof(line), stdin);
  } while (sscanf(line, "%f", &temp) != 1);
  
  printf("%.2f degrees C\n", convert_to_f(temp));

  return 0;
}
