How to convert int to character

#2

hey @Alfred
You can use to_string() function
it converts given integer to string type and then u can extract chars from it to add to char array/string

I send you the link of the code.plzz tell me my mistake

#4

Hey @Alfred

			string num=to_string(b); //converts b to string 
            for(int r=0;r<num.length();r++){ //traverse over string
                temp[j++]=num[r]; //add all digits as chars to array
            }

This is the logic for adding num
try to do the rest on ur own

#6 
#include<iostream>
#include<cstring>

using namespace std;
int main() {
	char a[1000];
	cin>>a;
	char temp[1000];
	temp[0]=a[0];
	int j=0;
	int k=0;
	for(int i=1;i<=strlen(a);i++){
		if(temp[j]!=a[i]){
			j++;
			int b=i-k;
			string num=to_string(b);
			for(int r=0;r<num.length();r++){
				temp[j]=num[r];
				j++;//added here
				}
			// j++;removed this
			temp[j]=a[i];
			k=i;
       }
	}
	for(int i=0;i<strlen(temp);i++){
		a[i]=temp[i];
	}
	a[strlen(temp)]='\0';
	for(int i=0;i<strlen(a);i++){
		cout<<a[i];
	}
	return 0;
}
