#include <time.h>

int main(void)
{
int stime;
long ltime;
int thisRandomNumbe r;
int userinput;
int userTries;

/* get the current time and then send the random number */
ltime= time(NULL);
stime= (unsigned) ltime/2;
srand(stime);

//calculate a random number between 1 and 100 */
thisRandomNumbe r= rand() %100 + 1;

userTries=0;

do{
printf("Guess the random computer generated number:\n");
scanf("%d",&use rinput);

if (userinput == thisRandomNumbe r){
printf("That's the number!\n");
}
else if (userinput > thisRandomNumbe r){
printf("Your guess is higher than the number.\n");
}
else if(userinput < thisRandomNumbe r){
printf("Your guess is lower than the number.\n");

userTries++;

}
while (thisRandomNumb er!=userinput);

printf("\nCongr atulations! That is the number! It took you %d tries", userTries);


return 0;
}

You have two basic errors.

ltime= time(NULL);

ltime is a long whereas the time function returns a time_t.
The ltime needs to be a time_t.

The second error is your do-while loop. There is no while part.
