For loops

         As we have seen already about the if statements, now let us see about the for loops. Nested for loops are a bit difficult to understand as it could be asked in different shapes used in mathematics.

A. PROGRAM:

#include<stdio.h>

#include<string.h>

void main()
{
int i,j;

for(i=0;i<=5;i++)
{
  for(j=0;j<=5;j++)
  {
   printf("%d",i);
  }

  printf("\n");

}

}

OUTPUT:

000000
111111
222222
333333
444444
555555

B. PROGRAM:

#include<stdio.h>
#include<string.h>
void main()
{
int i,j;
for(i=0;i<=5;i++)
{
for(j=0;j<=i;j++)
{
printf("%d",i);
}
printf("\n");
}
}

OUTPUT:

0
11
222
3333
44444
555555

C. PROGRAM:

#include<stdio.h>
#include<string.h>
void main()
{
int i,j;
for(i=0;i<=5;i++)
{
for(j=5;j>=i;j--)
{
printf("%d",i);
}
printf("\n");
}
}

OUTPUT:

000000
11111
2222
333
44
5

PROGRAM:

#include<stdio.h>
#include<string.h>
void main()
{
int i,j;
for(i=0;i<=5;i++)
{
for(j=5;j>=i;j--)
{
printf("%d",j);
}
printf("\n");
}
}

OUTPUT:

543210
54321
5432
543
54
5

PROGRAM:

#include<stdio.h>
#include<string.h>
void main()
{
int i,j;
for(i=0;i<=5;i++)
{
for(j=0;j<=i;j++)
{
printf("%d",j);
}
printf("\n");
}
}

OUTPUT:

0
01
012
0123
01234
012345

PROGRAM:

#include<stdio.h>
#include<string.h>
void main()
{
int i,j;
for(i=0;i<=5;i++)
{
for(j=5;j>=5-i;j--)
{
printf("%d",j);
}
printf("\n");
}
}

OUTPUT:

5
54
543
5432
54321
543210
