Convert a string to hexadecimal ASCII values in C++

In this tutorial, we will be discussing a program to convert a string to hexadecimal ASCII values.

For this we will be provided with a string of characters. Our task is to print that particular given string into its hexadecimal equivalent.

Example

 Live Demo

#include <stdio.h>
#include <string.h>
//converting string to hexadecimal
void convert_hexa(char* input, char* output){
   int loop=0;
   int i=0;
   while(input[loop] != '\0'){
      sprintf((char*)(output+i),"%02X", input[loop]);
      loop+=1;
      i+=2;
   }
   //marking the end of the string
   output[i++] = '\0';
}
int main(){
   char ascii_str[] = "tutorials point";
   int len = strlen(ascii_str);
   char hex_str[(len*2)+1];
   //function call
   convert_hexa(ascii_str, hex_str);
   printf("ASCII: %s\n", ascii_str);
   printf("Hexadecimal: %s\n", hex_str);
   return 0;
}

Output

ASCII: tutorials point
Hexadecimal: 7475746F7269616C7320706F696E74
