New page

== Binary to Decimal ==

This is my first practice. I got a bit confused with the code when I first met the problem, but in the end I got it.

‎<syntaxhighlight lang="c" line style="border: 1px solid red;">

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>

int btod(char *binary)
{
int i;
int decimal = 0;
int place = 0, temp = 0;

for(i = strlen(binary) - 1; i >= 0; --i)
{
if ((binary[i] == '0') || (binary[i] == '1'))
{
temp = binary[i] - '0';
}
else
{
printf("error: not a valid binary number\n");
exit(0);
}

decimal += temp * pow(2, place);
place++;
}

printf("the decimal number of this binary number is: %d\n", decimal);

return decimal;
}

int main(void)
{
char binary[10];
scanf("%s", binary);

btod(binary);

return 0;
}
