Sure! Here is a step-by-step guide to write a program in C to convert a binary number to a hexadecimal number system:

Step 1: Include the necessary header files:

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

Step 2: Define the main function:

int main() { // Your code goes here return 0; }

Step 3: Declare the variables:

int binary, decimal = 0, i = 0, remainder; char hexadecimal[20];

Step 4: Take user input for the binary number:

printf("Enter a binary number: "); scanf("%d", &binary);

Step 5: Convert binary to decimal:

while (binary != 0) { remainder = binary % 10; decimal += remainder * pow(2, i); binary /= 10; i++; }

Step 6: Convert decimal to hexadecimal:

i = 0; while (decimal != 0) { remainder = decimal % 16; if (remainder < 10) hexadecimal[i] = remainder + 48; else hexadecimal[i] = remainder + 55; decimal /= 16; i++; } hexadecimal[i] = '\0';

Step 7: Reverse the hexadecimal string:

strrev(hexadecimal);

Step 8: Print the hexadecimal number:

printf("Hexadecimal number: %s\n", hexadecimal);

Step 9: End the program:

return 0;

That's it! You have successfully written a C program to convert a binary number to a hexadecimal number system.
