Some question on while loop

Find outputs :

1.

#include<stdio.h>;
void main()
{
    int i = 1;
    while ( i <= 10 )
    {
        printf("value of i is %d.n",i);
        i = i+1;
    }
}

OUTPUT :

value of i is 1. value of i is 2. value of i is 3. value of i is 4. value of i is 5. value of i is 6. value of i is 7. value of i is 8. value of i is 9. value of i is 10.

2.

#include<stdio.h>;
void main()
{
    int i = 10;
    while ( i >;= 1 )
    {
        printf("value of i is %d.n",i);
        i = i-1;
    }
}

OUTPUT :

value of i is 10. value of i is 9. value of i is 8. value of i is 7. value of i is 6. value of i is 5. value of i is 4. value of i is 3. value of i is 2. value of i is 1.

3.

#include<stdio.h>;
void main()
{
    int i = 1;
    while ( i <= 10 )
    {
        printf("value of i is %d.n",i+1);
        i = i+1;
    }
}

OUTPUT :

value of i is 2. value of i is 3. value of i is 4. value of i is 5. value of i is 6. value of i is 7. value of i is 8. value of i is 9. value of i is 10. value of i is 11.

4.

#include<stdio.h>;
void main()
{
    int i = 1;
    while ( i <= 10 )
    {
        printf("value of i is %d.n",i*i);
        i = i+1;
    }
}

OUTPUT :

value of i is 1. value of i is 4. value of i is 9. value of i is 16. value of i is 25. value of i is 36. value of i is 49. value of i is 64. value of i is 81. value of i is 100.

5.

#include<stdio.h>;
void main()
{
    int i = 1;
    while ( i <= 10 )
    {
        printf("value of i is %d.n",i);
        i = i + 2;
    }
}

OUTPUT :

value of i is 1. value of i is 3. value of i is 5. value of i is 7. value of i is 9.

6.

#include<stdio.h>;
void main()
{
    int i = 1;
    while ( i <= 10 )
    {
    if( i%2 == 0)
        printf("value of i is %d.n",i);
        i = i + 1;
    }
}

OUTPUT : value of i is 2. value of i is 4. value of i is 6. value of i is 8. value of i is 10.

7.

#include<stdio.h>;
void main()
{
    char i = 'a';
    while ( i <= 'h' )
    {
        printf("value of i is %d.n",i); //keep %d in mind
        i = i + 1;
        }
}

OUTPUT : value of i is 97. value of i is 98. value of i is 99. value of i is 100. value of i is 101. value of i is 102. value of i is 103. value of i is 104.

8.

#include<stdio.h>;
void main()
{
    char i = 'a';
    while ( i <= 'h' )
    {
        printf("value of i is %c.n",i);
        i = i + 1;
    }
}

OUTPUT : value of i is a. value of i is b. value of i is c. value of i is d. value of i is e. value of i is f. value of i is g. value of i is h.

I think we know while loop very well now.
