You just need to wrap the code above into a loop that counts the number of tries. Somthing like:
#define MAXTRIES 5 // whatever maximum you decide on
int secret=52, tries=0;
for (tries = 0; tries < MAXTRIES; tries++)
printf("Enter a guess number between 1 to 100\n");
Note that your test for too high and too low are the wrong way round.
