How to convert a character chain into a ASCII-CodePudding

I would like to know how I could transform a character string to an ASCII value, such as "12ASD132 hello" in its ASCII values, and after that, if you have entered a character to skip an error

a greeting,

CodePudding user response：

To answer your first question: all C implementations I have ever seen store their characters in ASCII, so if your implementation is like that too, you can simply print character in the string as an integer:

#include <stdio.h>

int main() {
  const char * str = "12ASD132 hello";
  for (const char * p = str; *p; p  ) {
    printf("%d\n", *p);
  }
}

char *str = "12ASD132 hello";

printf("ch\tASCII\tASCII(HEX)\n");
while(*str)
{
    printf("'%c'\t%d\t0xx\n", *str, *str, *str);
    str  ;
}
