I tried to use writeStr to print out if the Hex converted to a decimal but all I get is the input i passed thru strToInt.

for example i chose A and it prints out an A but i wanted to print out a 10

Code:

#include <stdio.h>
#include "readStr.h"
#include "writeStr.h"
#include "strToInt.h"
#define BUFFER_SIZE 33
#define HEX_SIZE 9
#define BIN_SIZE 33
#define DEC_SIZE 11
#define BASE_SIZE 2
int main()
{
char input[BUFFER_SIZE];
char base[2];
unsigned int x;
writeStr("\nEnter the base of the value to be converted");
writeStr("\n d-decimal, h-hexadecimal, b-binary: ");
readStr(base, BASE_SIZE);
if(base[0] =='d' || base[0] =='D')
{
writeStr("Enter the Decimal Value: ");
readStr(input, 11);
}
else if(base[0] =='h' || base[0] =='H')
{
writeStr("Enter the Hex Value: ");
readStr(input, 9);
}
else if(base[0] =='b' || base[0] =='B')
{
writeStr("Enter the Binary Value: ");
readStr(input, 33);
}
else
{writeStr("Invalid Input - Goodbye");}
strToInt(input, base[0]);
writeStr(input);
return 0;
}

Code:

int strToInt(char *string, int base)
{
int decimal_val;
int result = 0;
int i;
if(base == 'h' || base =='H')
{
/* Goes through each value of string*/
for ( i = 0 ; string[i] != '\0' ; i++ )
{
/* The conversion */
decimal_val =
'0' <= string[i] && string[i] <= '9' ?
string[i] - '0' :
'a' <= string[i] && string[i] <= 'f' ?
string[i]- 'a' + 10 :
'A' <= string[i] && string[i] <= 'F' ?
string[i]- 'A' + 10 :
0;
result = result * 16 + decimal_val;
}
}
return result;
}
