I need some help I need to write a program that a user inputs a string of 32 0's and 1's representing a binary number. then I need to convert the binary integer to its base 10 representation and then back.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
long BinaryToDecimal(const char * pstrBinary)
{
int intLoop=0;
long lngReturn=0L;
long lngMultip=1L;
for (intLoop=0; intLoop < (int)strlen(pstrBinary); intLoop++)
{
if ('1' == pstrBinary[intLoop])
{
lngReturn += lngMultip;
}
lngMultip *= 2;
}
return lngReturn;
}
char * DecimalToBinary(long lngDecimal)
{
static char strReturn[128]={0};
_ltoa(lngDecimal, strReturn, 2);
return strReturn;
}
int main(void)
{
long lngDecimal = 7;
char * pstrBinary = "111";
printf("B2D=%ld\nD2B=%s\n", BinaryToDecimal(pstrBinary),DecimalToBinary(lngDecimal));
}
