ok, Thank you very much for your help...
...hmmm, how am I going to open this file, automatically, right after the user presses any key.. I mean, to pop it up on the screen, the result?
int main ()
FILE * testFile;
char name ;
testFile = fopen ("testFile.txt","w");
printf("Enter your name here: ");
printf("Enter your age: ");
fprintf (testFile, "The name you have inputed is: %s", name);
fprintf (testFile, "\nYour age is: %i", age);
