Base conversion in c ?

Question

/* Program to convert from one base to another */
#include <stdio.h>
int main(void)
{
char conversion_values[16] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'};
int num, base, converted_base[64], index = 0, index_store ;

// Get base and number
printf("Enter a number :");
scanf("%d", &num);
printf("Enter a base:");
scanf("%d", &base);

// Begins
do{
converted_base[index] = num % base;
index++;
num = num / base;
}while(num != 0);

for (--index; index >= 0; index--){
index_store = converted_base[index];
printf("%d\n", conversion_values[index_store]);
}
}

It returning unpredictable errors Why can anyone help me ?

Answer 1

You are printing char with "%d", and since it's a number, you don't need a newline.

You can also consider using putchar()
