C class is opening.

[someboddy]

Type this program:

#include<stdio.h>

 

void main(){

int a[5],b[5],c[5],i;

for (i=0;i<5;i++){

 printf("ngive me two numbers('a,b') ");

 scanf("%d,%d",&a,&b);

 c=a+b;

}

for (i=0;i<5;i++){

 printf("n %d+%d=%d",a,b,c);

}

printf("nnn");

}

 

there are parts here that I have allrady explaind, so I only explain the new thing: the array.

 

array is a set of variables that have serial numbers. when you want to use one of the variables in the array, you use it like this: <array name>[<variable serial number>]. for example: bla[5],x[7],set[9].

 

array is defined like a normal variable, only that a array have a "["&"]" around the number of variables. for example:

int thing[3];

defines a array with a place for 3 integer variables.

 

the serial number of the first variable in the array is 0. for example:if we have a array: staff[6], then the variables are: 'staff[0]','staff[1]','staff[2]','staff[3]','staff[4]' and 'staff[5]'.

 

instend of puting a number inside the "["&"]", you can put an integer in it, like something. this makes arrays extreamly useful in for loops.

[someboddy]

this time I have two simple programs:

#include <stdio.h>

 

void main(){

float a,b,c;

printf("nnGive me two numbers ");

scanf("%f,%f",&a,&;

c=a+b;

printf("n %f+%f=%fnn",a,b,c);

}

 

this is a simple adding program, but it have diferent from the program in the second lesson: it uses real numbers, that mean that we can do 4.79+5.3, for example.

using real numbers it's vwry similar to using integers but when you defining the variable, write "float " instend of "int ", and when using it in a "printf""scanf", write "%f" instend of "%d".

 

and one more thing: you cant put a real number in a integer.

[someboddy]

type this program:

#include <stdio.h>

 

void main(){

char anser;

printf("nnDo you like me?(y/n) ");

scanf ("%c",&anser);

if (anser=='y') printf("nI like you toonn");

if (anser=='n') printf("nThis means war!!!nn");

}

 

the char is a single character variable.

[someboddy]

type this program:

#include<stdio.h>

void main(){

char name[100];

printf("nnWhat's your name? ");

scanf("%s",&name);

printf("Hello %snn",name);

}

 

when you make an array of char's, you can use it as a string, but instend of typing "%c", type "%s".

These are the basic of c, and as soon as I whill learn C++, I whill teach you that too.

[emsley]

Just one question?

What the hell would it do if i learned it?

People who talk programing are crazy

[someboddy]

You will be able to create programs and games.

[emsley]

I dont want to "clutter" your lessons up but what software do i need to use this programming, do you have any sites were i can get the basics.

Is c+ used on the internet for designing webpages,

Whats the best programming i can learn to design webpages.

Sorry to drill you with questions.

[someboddy]

If you are planing to write in HTML, learn Javascript, and if you want to write complex programs, use Java.

If you are using front-page, learn visual-basic. all of the office programs sopport it.
