Binary To Decimal Conversion in C

/* Write a C program to convert the given binary number into its equivalent decimal */

#include

void main()
{
int num, bnum, dec = 0, base = 1, rem ;

printf(“Enter the binary number(1s and 0s)\n”);
scanf(“%d”, &num); /*Enter maximum five digits or use long int*/

bnum = num;

while( num > 0)
{
rem = num % 10;
dec = dec + rem * base;
num = num / 10 ;
base = base * 2;
}

printf(“The Binary number is = %d\n”, bnum);
printf(“Its decimal equivalent is =%d\n”, dec);

} /* End of main() */

/*—————————————————
Outpput
Enter the binary number(1s and 0s)
1010
The Binary number is = 1010
Its decimal equivalent is =10
