#include <stdio.h>
#include <string.h>
 
int main()
{
    char s[64] = "sdjfh1@", s_hex[128];
     
    printf("s: %s\n", s);
     
    memset(s_hex, 0, sizeof(s_hex));

    int i, j;     
    for(i = 0, j = 0; i < strlen(s); i++, j += 3) { 
        sprintf((char*)s_hex + j,"%02X ", s[i]);
    }
    s_hex[j] = '\0'; 
     
    printf("hex: %s\n", s_hex);
     
    return 0;
}

     
/*
       
run:
 
s: sdjfh1@
hex: 73 64 6A 66 68 31 40

*/
