    Need some advice

    i have this code to convert dinary to decimal but when i enter a binary number all it does is return the number of digits i typed i.e. if i typed 110010 it should return 50 but I get 6. Any help/advice would be greatly appreciated.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    /*function prototype*/
    int bin2dec(int binar4y);
    
    int main()
    {
        int binary;
        int decimal;
        
    
         printf("The decimal equivalent = %d\n",bin2dec(binary));
            
    getchar();
    getchar();
    return 0;
    }
    
    int bin2dec(int binary)
    {
             
             int b=0;
             int num[10];
             int i=0;
             int t=0;
             
             printf("Enter Binary Number\n");
             scanf("%d", &binary);
             while(binary != 0)
             {
              num[i] = binary % 10;
              binary = binary / 10;
              if(num[i] != 1 && num[i] != 0)
               t = 1;
              i++;
             }
             num[i] = 2;
             binary = 1;
             for(i = 0; num[i] != 2; i++)
             {
              b = b + num[i] * binary;
              binary = binary * 2;
             }
            
    }

    Perhaps bin2dec should return a value.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
