Guessing Game Questions

Guessing game that I got from a youtube video and wanted to ask a few questions that I didn't get. One what is the point of the else outofGuesses=1 part? Secondly when do you use one equal sign and when to use 2. Last but not least was there an easier way to do this like using a for statement?

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

int main(void) 
{
    int secretNumber= 5;   
    int guess; 
    int guessCount=0; 
    int guessLimit=3;
    int outofGuesses=0; 

    while(guess !=secretNumber && outofGuesses ==0)
    { 
        if(guessCount< guessLimit)
        { 
            printf("Enter a number between 1 and 10:"); 
            scanf("%d", &guess); 
            guessCount++; 
        } 
        else 
        { 
            outofGuesses =1; 
        } 
    } 
    if(outofGuesses==1) 
    { 
        printf("You lost!");
    } 
    else
    { 
        printf("You win!");  
        return 0;   
    } 
}

What is the point of the else outofGuesses=1 part?

It is meant to be a flag or an indicator. In this case, 1 represents true and 0 represents false

When do you use one equal sign and when to use 2?

As pointed out by @am121 in the other answer, use = for assigning a value to a variable and == while checking if two values are equal

Was there an easier way to do this like using a for statement?

First off, the program has a bug. The variable guess is not initialized and has undefined behavior. For example, if the guess is same as secretNumber, the person wins the game without playing. For this program, it should be assigned any value NOT equal to secret number

Same thing using for loop:

#include <stdio.h>

int main(void) 
{
    int secretNumber= 5;   
    int guess = 0; //Some value not equal to secretNumber 
    int guessLimit=3;

    for(int guessCount=1; guess!=secretNumber && guessCount<=guessLimit; guessCount++){ 
        printf("Enter a number between 1 and 10:"); 
        scanf("%d", &guess);             
    } 

    if(guess == secretNumber)
    { 
        printf("You win!");
    } 
    else
    {
        printf("You lost!");
    }
}

All of that is extremely basic, and if you have to ask, then you should look for a better teacher/tutorial

= is used to assign a value to a variable.

== is used to compare two values.

outofguesses=1 assigns the value 1 to that variable when you run out of guesses; it causes the comparison inside the 'while' to fail and the program flow to skip it to the finishing portion.
