Find the output of C#.Net programs | Loops | Set 3: Enhance the knowledge of C#.Net Loops concepts by solving and finding the output of some C#.Net programs.
Question 1:
using System;
namespace Demo
{
class Program
{
//Entry point of the program
static void Main(string[] args)
{
int num = 5;

{
Console.WriteLine(i * j);
}
}
}
}
Question 2:
using System;
namespace Demo
{
class Program
{
//Entry point of the program
static void Main(string[] args)
{
int num = 5;
for (int i = 0;int j = 0; i < num; i++, j++)
{
Console.WriteLine(i * j);
}
}
}
}
Question 3:
using System;

{
class Program
{
//Entry point of the program
static void Main(string[] args)
{
int num = 5;
for (int i = 1; i <= num; i++)
{
for (int j = 1; j <= i; j++)
Console.Write(j + " ");
Console.WriteLine();
}
}
}
}
Question 4:
using System;
namespace Demo
{
class Program
{
//Entry point of the program
static void Main(string[] args)
{
int num = 5;
for (int I= 1; I <= num; I--)
{
if (I == (int)Math.PI)
continue;
Console.WriteLine(I);
}
}
}
}
Question 5:
using System;
namespace Demo
{
class Program
{
//Entry point of the program
static void Main(string[] args)
{
int num = 5;
for (int I= 1; I <= num; I++)
{
if (I == (int)Math.PI)
continue;
Console.WriteLine(I);
}
}
}
}
c# programming
Answer 1:
Output:
Explanation:
In the above program, we created a variable num with initial value 5.
Now look to the loop iterations:
Iteration1: i=0 , j =0, here loop condition is true It will print 0 Increase the value of 'i' and 'j' Iteration2: i=1 , j =1, here loop condition is true It will print 1 Increase the value of 'i' and 'j' Iteration3: i=2 , j =2, here loop condition is true It will print 4 Increase the value of 'i' and 'j' Iteration4: i=3 , j =3, here loop condition is true It will print 9 Increase the value of 'i' and 'j' Iteration5: i=4 , j =4, here loop condition is true It will print 15 Increase the value of 'i' and 'j'Now condition will false, because the value i is 5, which is not less than num, and the loop will terminate.
Answer 2:
Output:
Explanation:
The above program will generate multiple errors because we did not use correct syntax in the for loop, which is given below,
for (int i = 0;int j = 0; i < num; i++, j++)The correct syntax is given below:
for (int i = 0,j = 0; i < num; i++, j++)Answer 3:
Output:
Explanation:
In the above program, we created a variable num initialized with 5. Here, we used a nested loop, where the outer loop is used for the number of rows printed, And the inner loop will print execute according to the value of i.
For i=1; It will print 1 For i=2; It will print 1 2 For i=3; It will print 1 2 3 For i=4; It will print 1 2 3 4 For i=5; It will print 1 2 3 4 5Then the loop will terminate.
Answer 4:
Output:
Explanation:
The program will execute infinite time because we used a post decrement operator instead of an increment operator that's why condition will always true and the loop will never terminate.
Answer 5:
Output:
Explanation:
In the above program, we created a variable num initialized with 5. Here, loop will execute 5 times. In the loop body, we used PI property of Math class and typecast it into integer then it will be 3. When value of variable I will 3 then continue statement skip below WriteLine() statement. That's why it will not print '3' on the console screen.
Note: The continue is a skipping statement. It is used to skip, one or more than one statement based on the specified case.
