Not generating the 1000 random numbers needed

Question

I am developing a C program that randomly generates a thousand numbers and that in the end appears the largest and smallest among them. For this, I am using the rand().

But I have a problem. When I run only less than 300 numbers are generated and not 0 to 1000. But 707 to 1000.

Look down at what I’ve done:

include stdio.h
include stdlib.h
include windows.h

main(){
   int numero,numero2;
   int total1 = 0;
   int total2 = 1001;

   for (numero = 1; numero != 1001; numero++){
       numero2 = rand () % 1000;
       printf("Numero %d: %d \n ",numero,numero2);

       if (numero2 > total1){
           total1 = numero2;
       }

       if (numero2 < total2){
           total2 = numero2;
       }
   }

   printf("\n");
   printf("O maior numero e: %d \n\n",total1);
   printf("O menor numero e: %d \n\n",total2);

   system("pause");
   return 0;
}

Where am I going wrong?

Answer 1

Your code has several syntax errors and was not (before editing, which should not be done) well disorganized, this makes it difficult to understand it. Even you who wrote it end up getting lost in it. The nomenclature of variables would also help to better describe what the code does.

But the main problem was the misuse of the operator != (operator testing the difference, that is if the operands are different from each other, that has whichever difference from one to the other) when should use < (operator testing whether the first operand is less than the second). The first does while it is different, ie it is to do nothing. I do not know how I was doing something. The second operator, as the reading itself describes it does while "is less than". So numero starts at 1 and goes on counting until it reaches 1001. While it is less than 1001, it goes on repeating, so it will repeat a thousand times.

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

int main(){

    int numero, numero2;
    int total1 = 0;
    int total2 = 1001;
       
    for (numero = 1; numero < 1001; numero++) {
        numero2 = rand () % 1000;
        printf("Numero %d: %d \n ", numero, numero2);
        if (numero2 > total1) total1 = numero2;
        if (numero2 < total2) total2 = numero2;
    }
    printf("\n");
    printf("O maior numero e: %d \n\n",total1);
    printf("O menor numero e: %d \n\n",total2);
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.

In it I did a little different, I put the srand() to start sowing a little better the pseudorandom numbers.
