raynold: wrote this program in c and its working perfectly, just wrote this now in c++..

#include<iostream>

using namespace std;
int main()
{
int a, b, c, num;
int choice;
cout<< "\t\t\t welcom choose your operation\n";
for ( num = 1; num <= 7; num++)
{
cout<< "\t\t\t -1 addition\n \t\t\t -2 substraction\n \t\t\t -3 multipication\n";
cout<< "\t\t\t -4 exit\n ";
cin>> choice;
if (choice == 1)
{
cout<< "enter first value :";
cin>> a;
cout<< "enter second value :";
cin>> b;
c = a+b;
cout<< " addition is" << c<<endln;
}
if (choice == 2)
{
cout<< "enter first value :";
cin >> a;
cout<< "enter second value :";
cin >> b;
c = a - b;
cout<< " the subtraction is << c<<endln;
}
if (choice == 3)
{
cout<< "enter first value :";
cin>> a;
cout<< "enter second value :";
cin>> b;
c = a * b;
cout<< " the multiplication is << c<<endln;
}
if (choice == 4)
{
cout<< "\t\t\t thanks for using mini calcultor bye\n";
break;
}
if ( choice >= 5)
{
cout<< "\t\t\t invalid choice try again\n";
}
}
}

adelolaa:


there is so many error in ur codes. av corrected it though . eg. nothing like endln and u forgot to put end ( " ) quote for some string.





here is d corrected one

adelolaa: join me to solve this seven questions this week



Assignment for chapter five (while loop, for loop, do-while loop)

HOD: ALEX ALLAIN

STUDENT: XARMZON

COURSE: JUMPING INTO C++


Q1: write a program that prints out then entire lyrics to a full rendition of "99 bottles of beer"

Q2: write a menu program that let the user select from a list of options, and if the input is not one of the options, reprint the list.

Q3: write a program that compute a running sum of inputs from the user, terminate when the gives an input of zero (0)

Q4: write a password prompt that give a user only a certain number of password entry attempts, so that the user cannot easily write a password cracker.

Q5: try writing each practise problem with each kind of loop, notice which loops work well for each kind problem.

Q6: write a program that displays first 20 square numbers.

Q7: write a program that provides the option tallying up the result of a poll with 3 possible values. First input to the program is the poll question; the next three input are the possible answers. The first answer is indicated by 1, the second by 2, the third by 3, the answers are tailed until a zero (0) is entered. The program should then show the results of the poll try making a bar graph that show the results properly scale to fit on your screen no matter how many results were entered.

Good luck!!!!!!

adelolaa: thank you all. I will post my solution to question 2 and 3 dis nite. question 1 and 4 is solve by u

wisemania: @raynold, its better u just stick to one lang,if its c ,den let it be, if its cpp den let it be....coz i kw u wudnt like me to com here creating awearness dat i kw html,css,javascript,c,cpp....
I kud aswell ryt all d programs in js,c and cpp if i so wish,bt it wudnt be a good idea.....i beg!
Ur codes pure sha....nize wrk....

wisemania: //Soln in c to Q 6--Square program

#include <stdio.h>
#include <math.h> //include d math header file, so as to invoke d pow() function

#define TWENTY 20 // sybolic
constant
int main()
{

int num, counter;

printf("this program prints the squares of the first 20 numbers(0-19)\n";

printf("numbers | squares\n";

for (counter = 0, num = 0 ; counter < TWENTY; counter++, num++)
printf("%2d %12d\n", num, pow(num, 2));

return 0;
}

raynold: nice.. any other to do this??

wisemania:
sur boss...
U can remove:
#define TWENTY 20 from d program, and use just "20" 4ur test in d if stat...
And also d pow() function ...u sure can use just "num * num"
........
//Soln in C to Q 6--using a "do while " loop.

#include <stdio.h>

{
int num, i;
i = 0;

do{
printf("%2d %10d", num, num * num) ;
i++, num++;
}
while (i < 20) ;

Leopantro: have got my eye on this thread for a while it says for beginners and i'm in the class below dumm.ies. was wondering if i could utilize any of the codes above in the android app "c4droid" to learn c++?

raynold: really nice program. love the way a customer is able to order more than one drinks unlike mine..

wisemania:

thanks bro....u inspired it...
U alreedy kw dat "scanf("%d", order)" tells d compiler to prompt d user to enter one digit number...
Putting it in a while loop tells d compiler to kip on requesting for a digit number..so once a digit is entered, the reamaing nested "if" loop is being trigered.....
Bt if a non digit number is entered,...eg characters like (a-z,; . : - = @ etc) dat arnt numbers(dont fit into the scanf() digit format specifier"%d" den d inner if loops wont be executed....thus the program is terminated....
