Duaa-07

i'm trying to build a calculator with the basic operations ( +, -, * ,/) and the root square as well as the decimal point

but when clicking on the form on the root square or the decimal point they're still not working as if it's concatenating the numbers although i did parse them

and i'm trying to do any operation for more than just 2 inputs and something is still wrong it also seems that the numbers or actually certain numbers are being concatenated instead of applying the operation on

so can you please help me?

thanks !

here 's the code

https://drive.google.com/file/d/0B6NPKZsgNLOCZEFNa...

is it even correct?

In a high school graduating class of 100 students, 54 studied mathematics, 69 studied mechanics, and 35 studied both mathematics and mechanics. If one of these students is selected at random, find the probability that:

a. The students took mathematics or mechanics

b. The student did not take either of these subjects

c. The student took mechanics but not mathematics

i just need c ,but i'd like to make sure a and b are correct also

a-0.88

b-0.22

thanks

like how simple should it be or would kids understand such ideas? whats the perfect age to teach them how to code or just the basics of coding

would you teach yours how to code? or would like him/her to show interest first?

i want to learn both but which one should go first which is easier?and what are the programs that i need to download to start working on the codes using each?

i have this code that creates a table and asks the user to enter the values of IDs and makes sure that the id is a number and breaks if the user inputs it 3 times not a number and prevents the user to input an id number that already exists

i only need some help on how to prevent the user all i got out with is just compering the ID[i] with one previous value and not all the previous values

<script>

var i;

var j;

var w;

var con=0;

var ID=new Array(5);

var grade;

var sum=0;

var names=new Array(5);

names[0]="Duaa";

names[1]="Chaza";

names[2]="Ola";

names[3]="Ghina";

names[4]="Hassan";

document.writeln("<table border='1'>");

for(i=0;i<names.length;i++)

{

con=0;

ID[i]=prompt("Enter The Id number of "+names[i],"ID number");

while(isNaN(ID[i])&&con<2)

{

con++;

ID[i]=prompt("Enter The Id number of "+names[i],"ID number");

}

/* This loop */

for(w=0;w<ID.length;w++)

{

if(ID[i]==ID[i-1])

{

window.alert("You Have Already Entered That Id Number!");

break;

}

}

if(con==2)

{

window.alert("You are a loser!");

break;

}

else

{

/*other details and stuff i'm already done with */

}

}

using C,Converting each \t to a number of spaces ... Ex ,if my tabs.txt contains

This file has. too many. tabs. where each space above is actually a \t character, then the file myspaces.txt should look like the following if n=2, This. file has too many tabs. can my if statment be like if (c=='\t') then i d print a space ? i do have the code but its not runnging dunno why :-/

#include<stdio.h>

#include<stdlib.h>

int main()

{

char d;

FILE * fin = fopen("mytabs.txt", "r");

FILE * fout = fopen("myspaces.txt", "w");

int n;

printf("Enter n: ");

scanf("%d", &n);

while(fscanf(fin, "%c" ,&d)!=EOF)

{

if(d =='\t')

{

for(i=0;i<n;i++)

{

fprintf(fout , " ");

}

}

else {

fprintf(fout, "%c", d)

}

}

fclose(fin);

fclose(fout);

system("pause");

return 0;

}

or what are the steps that i should follow in-order to create something similar ?

http://templates.entheosweb.com/template_number/34... what flash builder ?? where to start etc??

and

http://livedemo00.template-help.com/wt_37255/index... this one seems the easiest if am not wrong

if i' can't be able to get these codes then how can i do something like them esp the first two any help? what do i need ?how to ..etc

should i use ?, i'm trying my best to not use java and css but anyways what ideas so you think make a cv greater add colors video maybe ? since its a webpage

thank you:D
