//so i will paste code with question above here and try to make this less complicated , most solutions will be inside comment so you can remove that try that code

//<QUESTION 1> 
//1,2,3,4 row  like this 
/*1,2,3,4
  1,2,3,4
  1,2,3,4
  1,2,3,4
*/

//Answer 

#include <iostream>
using namespace std;

int main(){
  
  cout<<"welcome here i will solve question 1"<<endl;
  int a; // a is integer
  cin>>a;// save input as a

  cout<<" your input is "<<a<<endl;
  int i;
  i=1;

  while(i<=a){ //this while is to repeact row after line
    int j;
    j=1;
    while(j<=a){

/* <OUESTION 6 > 
Printing half pyramid using Alphabets
a 
b b 
c c c 
d d d d 

TO solve this we need a logic or understanding of conversion  so here is logic understand it first 
   
    char b = 'd';
    int c = b - 'a' + 1;
    cout << c<<endl; 

    char final ;
    final = 'a' + c - 1;
    cout<<final;

<ANSWER> 
#include <iostream>
