Lesson 3 first exercise

[Bleh]

it says: Using a while loop, write a program that prints alphabets 'a' through 'z' in seperate lines. Use %c in your format string. You can increment a character type variable with ++ operand.

I don't get how to go up one letter each time in the loop. Or what it means by format string, what is the format string? If anyone can help me, reply here please or E-Mail me at xatrix_99@excite.com    Thanks.

int ch=97;
while (ch<=122) {
        printf("%c",ch);
        ch++;
}

The format string is the string of characters that you use to format the output on the screen. You use %c to tell the program to print out a character, %d to print out an integer, %f to print out a float, etc.

[Mr. Cool]

% means to format something. e.g., %d=decimal integer, %c=character, %lf=double or dbl float, %f=float with a deimal point that ends with 16 numerals, &%hd= short decimal and so on.

this is usually decifiered by yoour declaration and intialization heading. eg;

[code:g4iajmu4]
int main(void)
{
float a=3;

printf("%f", &a);
return 0;
}[/code:g4iajmu4]

good luck and if you need anything else pls ask me.
