Nested For Loop:-
We will use more than one for loop using nested sequence using inner for loop and outer for loop. The outer for loop executes once then the inner for loop will be executed when the inner condition will be false then the outer for loop will again increase when the outer for loop condition will false then the loop will be terminated. We can create a pattern-based program using nested for loop.
for(init;condition;iteration)
{
for(init;condition;iteration)
{
Statement;
}
}
For example, if we want to create the following pattern:-
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
...............................................................................................................................
for(int i=5;i>=1;i--)
{
for(int j=1;j<=i;j++)
{
Console.Write(j+" ");
}
Console.WriteLine();
}
Another Example of Nested For Loop to display pattern based on alphabets:-
for(init;condition;iteration)
{
for(init;condition;iteration)
{
Statement;
}
}
For example, if we want to create the following pattern:-
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
...............................................................................................................................
for(int i=5;i>=1;i--)
{
for(int j=1;j<=i;j++)
{
Console.Write(j+" ");
}
Console.WriteLine();
}
Another Example of Nested For Loop to display pattern based on alphabets:-
class ForLoopExample
{
static void Main()
{
for (int i = 1; i <= 5; i++)
{
int asc = 65;
for (int j = 1; j <= 6-i; j++)
{
Console.Write((char)asc + " ");
asc++;
}
Console.WriteLine();
}
Console.ReadKey();
}
}
