I'm a bit confused about how to solve this warning and error

I have to make a code where a random number is generated between 1 and 100, and a user has to input numbers until they figure it out. At the end, it has to tell them how many guesses it took them to figure it out. I have one error and one warning, neither of which I know how to handle. I tried looking them up but I couldn't really find something to help me:

main.c: In function ‘main’:
main.c:18:26: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
         srand((unsigned) time(&t));
                          ^~~~
main.c:43:1: error: expected ‘while’ before ‘}’ token
 }
 ^
main.c:43:1: error: expected declaration or statement at end of input

Here's the code I'm working with for reference:

#include <stdio.h>
#include <stdlib.h>

int main() {

        char name[1024];
        int i, n;
        time_t t;
        int randNum;
        int userTries;
        int inpUser;

        printf("Please enter your name: \n");
        scanf("%s", name);
        printf("Hello %s\n, we're going to play a game where you guess a secret number. I will tell you if you're too high or too low, and I will also tell you at the end how many guesses you took.\n", name);

        //initializes the random number generator
        srand((unsigned) time(&t));

        //calculates a random number between 100 and 1*/
        randNum = rand() %100 + 1;

        do {
                printf("Guess a random number, but I bet you'll get it wrong:\n");
                scanf("%d", inpUser);
        if (inpUser == randNum) {
                printf("That's the number! Maybe I underestimated you.\n");
        }
        else if (inpUser > randNum) {
                printf("You're a little high there, bud.\n");
        }
        else if (inpUser < randNum) {
                printf("Maybe go a little higher next time?\n");

        userTries++;

        }
        while (randNum != inpUser);
        printf("Congratulations, you actually did it! That's the number! It took you %d tries, but you did it!", userTries);

        return 0;
    }

}
