If Statements wont stop?

[litzkrieg]

ok im sure this is just something small im missing but im still missing it when i compile this and select an amount when the program is running it prints everything, however i only want it to print for the selected number. how can make this so it only prints the number i select? oh and the program is supposed to print the row headers of a k-map for the selected number of variables.

Thank you

#include<stdio.h>
int main(void)
{
int a;
printf("Number of Variables (1-10): \n");
scanf("%i", &a);

if(a=1)
	{
		printf("\n0\n1\n");
	}
if(a=2)
	{
		printf("\n0\n1\n");
	}
if(a=3)
	{
		printf("\n00\n01\n11\n10\n");
	}	   
if(a=4)
	{
		printf("\n00\n01\n11\n10\n");
	}	   	   
if(a=5)
	{
		printf("\n000\n001\n011\n010\n100\n101\n111\n110\n");
	}	   	   
if(a=6)
	{
		printf("\n000\n001\n011\n010\n100\n101\n111\n110\n");
	}	   
if(a=7)
	{
		printf("\n000\n001\n011\n010\n100\n101\n111\n110\n");
	}	  	   
if(a=8)
	{

	}

	}	 	   	   	      	       
return a;
}

Sorry if its alittle wide i should have checked that, my bad sorry

'=' is assignment, '==' is equality.
Use 'else if' after your first 'if', it's better and faster. ( After all, 'a' can only have one value )

Perfect thank you just starting to learn this fun little lang.

Hey, don't mention it!
Keep it up, you're doing great. As a beginner, your primary goal must be to try to understand what the heck your compiler is talking about when there's an error!
