Need help fixing code

[skgbafa]

I'm creating a code for guessing a random number that a user put in. I come across a problem where I ask the user if the number generated was their number, and it always registers as a yes, even when I put a no. Any ideas on how to fix this?

#include <iostream>
#include <cmath>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;

int main ()
{
cout << "Think of a number between 0 and 10. Now let me try and guess it." << endl;
int a,b,y,n;
y = 90;
n = 60;
bool c;
/*planned values for variables:
a= their number
b= their value for if random number is true or false
if b=Y,y then c=true
if b=N,n then c=false
if c= true then "congrat i win"
if c= false then "boo i lose, lemme guess again" */
srand ( time(NULL) );
cout << endl;
cout << "Input your number. Don't worry, I wont know it." << endl;
//Here im going to set a limit on the input of the number so that it is between 1 and 10
cout << endl;
cout << "Your Number: ";
cin >> a;
cout << endl;
if (a >= 10 && a >= 1)
//If the number is out of the bounds, then I will have a message appearing for them to put in a number between 1 and 10.
{
	
	cout << "Sorry, " << a << " is either too high or too low. Using a number out of the range of 0" <<endl << "and 10 will make this program inoperable and will cause it to exit. Please try" <<endl << "again." << endl;
	cout << endl;
	cout << "Your Number (Between 0 and 10): ";
	cin >> a;
	if (a >= 10 && a >= 1)
	{
		cout << endl;
		cout << "The program will now exit." << endl << endl;
		system("pause");
		exit(0);
	}
} 
printf ("Is the number %d", rand () % 10);
cout << endl;
cout << endl;
cout << "y/n: ";
cin >> b;
cout << endl;
//Here I'll make it so that b is true or false
if (b = 90)
{
	c = true;
}
if (b = 60)
{
	c = false;
}
if (c = true)
//if c is true then say "wow i figureed out the number or something
{
	cout << "Yes! I succefully guessed your number!" << endl;
	//I would like to include an "it only took *#* many tries for me to guess it!"
}
if (c = false)
//if c is false, then go back and and ask random number, but dont repeat numbers if possible
{
	cout << endl;
	cout << "Hmm, that was wrong, let me try again.";
}



cout << endl; 
system ("pause");
return 0;
}

And I considered scrapping most of the if/true-false lines and going with a loop where it breaks when true. I've been learning C++ for about a month and I've only written math programs, so I'm willing to take any suggestions.

"=" is the assignment operator. In each of your if statements you should use "==" (comparison) (without quotes)

[feedmetotheforest]

it is better to use else if's after the first if, and else at the end, this website covers it

it would probably be better to do something like

#include <iostream>
#include <cmath>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
int main()

{

int var, boo=0;

cout<<"have a bash"<<endl;
cin>>var;


while(boo==0)
{
 int var2 = (rand()%10);
 
 if(var==var2){
   cout<<"well done to me!"<<endl;
   boo++;
   }
 else
   cout<<"woops"<<endl;

}

return 9;


}

each time the loop iterates a new random number is made, and the boo variable controls whether you leave the loop or not

except the <stdio.h> is pointless because <iostream> is the c++ equivalent. time.h >> ctime and stdlib.h>> cstdlib. and why are you using printf if your writing in c++
