When a loop resides inside of other loop .Nested loops are
useful while if there is a need of looping for each count of other turn of a
loop.
Syntax :
When we learn C language then we print many types of pattern
using nested loop. as follows
- Handling Matrix/2-D Array input/output
- Processing Range of similar Data like array
- Printing Series
- Structure operation
Now I am going to print following pattern using all three types of loop.
While loop example
int i,j;
i=1;
while(i<=5)
{
j=1;
while(j<=i)
{
printf("*");
j++;
}
printf("\n");
i++;
}
For loop example
for(i=1;i<=5;i++)
{
for(j=1;j<=i;j++)
printf("*");
printf("\n");
}
Do-while loop
i=1;
do
{
j=1;
do
{
printf("*");
j++;
}while(j<=i);
printf("\n");
}while(j<=5);
