void fun(char str[])
{
     int len=strlen(str);
     int i,j;
     for(i=len-1,j=2*len-1;i>=0;i--,j-=2)
     {
                str[j]=((int)str[i])%10 + '0';
                str[j-1]=((int)str[i])/10 + '0';
                }
     str[2*len]='\0';
     }

How can u do it in place??? The new string is longer.

void print_ascii(char str[] ){
int len = strlen(str);

int last_index = len - 1;

int i =0,j,count = 0;
int val;
while(count < len){

for ( j = last_index ; j >= i ; j -- )
str[j+1] = str[j];


val = str[i];
str[i] = '0'+(val/10);
str[i+1] = '0'+(val%10);



last_index++;

i = i + 2;
count++;

}
str[last_index + 1 ] = '\0';

printf("\n ans str = %s",str);
}

#include<conio.h>
#include<stdio.h>
#include<string.h>
int main()
{
char c[100];
int i=0;
printf("Enter the string :");
scanf("%s",c);
while(c[i]!='\0')
{

printf("%d",c[i]);
i++;
}
getch();
return 0;
}

void str_to_ascii(char *a)
{
  if(!a)
    return;
  else
  {
    int orig_len=strlen(a);
    int new_len=orig_len*2;
    int i,j,value;
    for(i=orig_len-1, j=new_len-1; i>=0; i--, j--)
    {
      value=a[i];
      a[j]=(int)'0'+(value%10);
      j--;
      value=value/10;
      a[j]=(int)'0' + value;
    }
    a[new_len]='\0';
}

Since we're working with "in-place", I'm assuming we're going to pass in something that's more edit-friendly (I'm using Java). So I'm using StringBuilder:

public class ToAscii
{
	public static void toAscii(StringBuilder sb)
	{
		int length = sb.length();
		int numberOffset = 0;
		for(int i = 0; i < length; i++)
		{
			String numberString = new String("" + (int)sb.charAt(numberOffset));
			sb.insert(numberOffset, numberString);
			numberOffset += numberString.length();
			sb.deleteCharAt(numberOffset);
		}
		System.out.println(sb.toString());
	}
}

A quick and dirty solution

#include <stdio.h>
void main()
{
stringtoascii();
}

void stringtoascii()
{

char *array="HELLOWORLD";

while(*array !='\0')
{
printf("The value of the string is %d\n",*array);
*array++;
}
}

//this is working fine
void print_ascii(char str[] ){
int len = strlen(str);
str=(char *)realloc(str,2*len*(sizeof(char)));
int i=0;
int j;

str[2*len]='\0';
for(j=(2*len)-1;j>=1;){
i=(int)j/2;
str[j] = (char)(48+(str[i]%10));
str[j-1] = (char)(48+(str[i]/10));
j=j-2;
}
printf("%s\n",str);
}

Assuming that input is only in uppercase...

void replaceCharsByASCII(std::string &input){

	int length = input.length() * 2;
	for(int i = 0; i < length; i+=2){
		int a = input[i];
		std::stringstream ss;
		ss << a;
		std::string g = ss.str();
		input.replace(i,1,g);
	}
	
	
}

public class StringToAscii {

	public static void main(String[] args) {
		
		char str[] = "HELLOWORLD".toCharArray();

		
		StringBuilder sb = new StringBuilder();

		for (int i=0 ; i<str.length ; i++){

			sb.append((int)str[i]);

		}

		System.out.println(" Final String " + sb.toString());
	}
}
