Octal to Hexadecimal Conversion in C

Octal to Hexadecimal Conversion in C

#include<stdio.h>

int main()
{
    int num;
    printf("Enter any octal number:\n");
    scanf("%o", &num);
    printf("Hexadecimal value is: %X\n", num);

    return 0;
}
  

📘 Explanation:

This C program converts an octal number into its hexadecimal equivalent using format specifiers.

• The %o format specifier in scanf() reads an octal number.
• The compiler internally converts the octal value into decimal.
• The %X format specifier in printf() prints the value in hexadecimal (uppercase).
• No manual conversion logic is required.

This is a simple and efficient way to convert octal to hexadecimal in C.

🧾 Sample Output:

Enter any octal number:
17
Hexadecimal value is: F
