Question

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints:

0
 1
  2
   3

Sample program:

#include <stdio.h>

int main(void) {
   int userNum  = 0;
   int i = 0;
   int j = 0;

   <STUDENT CODE>

   return 0;
}

2)

Given variables numRows and numCols (type int, already initialized), print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Variables already defined for your use are: int currRow, int currCol, and char currColLet. Print a space after each seat, including the last. Example output for numRows = 2 and numCols = 3:

1A 1B 1C 2A 2B 2C 

Answer 1

for(i=0; i<=(userNum); i++){
       for(j=1; j<=i; j++)
       cout << " ";
       cout << i << endl;
   }

Answer 2

Note: Program is implemented in C and CPP also.

Complete program in CPP:

1 #include iostream» 2 using namespace std; 3 int main(void) 5 6 7 8 9 10 int userNum-0 int i- 0; int j = 0; cout "Enter your number: "; cin >> userNum; //repeat until i exceeds userNum 12 13 14 //print i number of spaces for (J = 0; j〈i, j++) cout くく " " 16 17 18 19 20 21 //print number and new line cout くく ! くく endl; return 0;

Sample output:

Enter your number: 3 1 2 3 sh-4.39

Code to copy:

In C:

#include
int main(void)
{
   int userNum = 0;
   int i = 0;
   int j = 0;
   printf("Enter your number: ");
   scanf("%d",&userNum);
   //repeat until i exceeds userNum
   for(i=0;i<=userNum;i++)
   {
       //print i number of spaces
       for(j=0;j        {
           printf(" ");
       }
       //print number and new line
       printf("%d\n",i);
   }
    return 0;
}

In CPP:

#include
using namespace std;
int main(void)
{
   int userNum = 0;
   int i = 0;
   int j = 0;
   cout << "Enter your number: ";
   cin >> userNum;
   //repeat until i exceeds userNum
   for (i = 0; i <= userNum; i++)
   {
       //print i number of spaces
       for (j = 0; j        {
           cout << " ";
       }
       //print number and new line
       cout << i << endl;
   }
   return 0;
}
