It's not working ! Why ?

Question

#include<iostream>
using namespace std;

int main(){
int v_space=500;
int c[v_space],i;

for(i=0; i<v_space; i++)
c[i]=0;

char str[100];
int str_ln;
cout<<"enter the string \n";
cin>>str;
str_ln=strlen(str);
/////////////////////////////////////////////
for(i=0;i<str_ln;i++)
c[str[i]]++;
/////////////////////////////////////////////

cout<<"latters | used\n";
cout<<"---------------------------";
for(i=0;i<v_space;i++)
if(c[i]!=0)

Answer 1

Error is here:
for(i=0;i<str_ln;i++)
c[str[i]]++;

You need to use a map instead of array.

Answer 2

Or change it to
for(i=0; i<str_ln; i++)
c[(int) str[i]]++;

cout<<"letters \t|\t used\n";
cout<<"---------------------------";
for(i=0; i<v_space; i++)
if(c[i] != 0)
cout << (char) i <<"\t|\t "<< c[i] << endl;

Answer 3

create project in the playground, copy link and paste here

Answer 4

a working code:

Answer 5

lol, just create a new code and delete old one :)

Answer 6

it is to count the friquancy of letters in string

/*you can use it for any language keywoard
the only need is to extend the virtual space(v_space)

no need to remamber the ascii 😁 values of every
language ....*/

Answer 7

few lines are missing .....⬆️
due to word limit of questions.🤔

Answer 8

I don't know how to do it 🙄

Answer 9

the same code:
https://code.sololearn.com/c537ntWq8H1f/?ref=app
