    What's wrong here?

    Code:
    #include <stdio.h>
    
    int input;
    char msg[128];
    
    void decrypt()
    {
    	int i = 0;
    	while(i<128)
    	{
    		scanf("%i",input);
    		if(input == 30)
    			msg[i] = 0x41;
    		else if(input == 02)
    			msg[i] = 0x42;
    		else
    			return;
    		i++;
    	}
    }
    int main()
    {
    	decrypt();
    	printf("\n");
    	return 0;
    }
    I think that it's a scanf() problem, yet I get no errors when I compile. What do you think?

    scanf("%d",&input);

    Oh!

    Crud! I forget that... it's been so long since I use scanf(). Thanks!

    To obtain numbers properly, read this:
    http://faq.cprogramming.com/cgi-bin/...&id=1043284385

    >>msg[i] = 0x41;
    This isn't good practice, don't use hex numbers like that. This is much easier on the eyes, and more portable:
    >>msg[i] = 'A';
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
