int main(){
int binNum;
printf(“Enter the Binary Number”);
scanf(“%d”,&binNum);
Binary_to_Decimal(binNum);
return 0;
}

void Binary_to_Decimal(int binNum){
int power=0;
int decNum=0;
while(binNum>0){
int lastDigit= binNum%10;
decNum = decNum + (lastDigit*pow(2,power));
power++;
binNum=binNum/10;
}
printf(“The decimal of given number is %d”,decNum);
}
