rock paper scissors game in c. Can someone tell where my fault is?

Question

The computer always gives the same input.

For example :example or example2

As in the example, I always choose the rock and the computer always chooses the paper. What should I do to make the computer give a different result?

Probably there is something wrong with the last function but I couldn't find it. Can someone help me please?

enum Move {ROCK = 1, PAPER, SCISSORS}input;

int input, computerInput = 0;
int rock = 1;
int paper = 2;
int scissors = 3;
int computerPoint = 0, userPoint = 0;

printf(" ###### Welcome to Rock-Paper-Scissors Game ###### \n");
printf(" ### Rules: \n ### Press 1 for Rock \n ### Press 2 for Paper \n ### Press 3 for Scissors \n ### First one to reach 3 points will win. \n");

printf("Input your move : ");
scanf("%d", &input);


while(input < 1 || input > 3)
{
printf("Your input must be 1, 2 or 3 \n");
printf("Input your move : ");
scanf("%d",&input);
}
    
while(input == computerInput)
{
        printf("It's draw. \n");
        printf("Your Point is %d and Computer's point is %d \n",userPoint, computerPoint);
        printf("Input your move : ");
        scanf("%d",&input);
            
}


while(input != computerInput && userPoint < 3 && computerPoint < 3){
    
    switch (input)
    {
        
        case ROCK:
        if(computerInput == 2){
            printf("You picked Rock. Computer picked Paper. Computer got 1 point(s). \n");
            computerPoint++;            
        }
        else if(computerInput == 3){
            printf("You picked Rock. Computer picked Scissors. You got 1 point(s). \n");
            userPoint++;
        }
        break;
        case PAPER:
        if(computerInput == 1){
            printf("You picked Paper. Computer picked Rock. You got 1 point(s). \n");
            userPoint++;
        }else if(computerInput == 3){

enum Move getRandomMove(){
    int computerInput;
    srand(time(NULL));
    computerInput  = 1 + rand() %3;
    return computerInput;
}

After all the changes, this is the correct working and cleared version. Thank you very much to everyone who helped.

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

int main(void){

enum Move {ROCK = 1, PAPER, SCISSORS}input;
srand(time(NULL));
int computerInput;
int computerPoint = 0, userPoint = 0;

enum Move getRandomMove()
{
return (enum Move)(1 + rand() % SCISSORS);
}
