please help me with this questions

first one is:
"Write a program that inputs one five-digit number, separates the number into its individual digit and prints the digits separated from one another by three spaces each.[Hint: Use combinations of integer division and the remainder operation.]"

my code is like this:

Code:

---


#include <stdio.h>
 
int main()
{
 int num;
 
 printf("Enter a five-digit number:");
 scanf("%d",&num);
 
 printf("%d num/100000\n");
 num=num%100000;
 printf("%d num/10000\n");
 num=num%10000;
 printf("%d num/1000\n");
 num=num%1000;
 printf("%d num/100\n");
 num=num%100;
 printf("%d num/10\n");
 num=num%10;
 
  return 0;
}

---

but it does no work. what is the mistake please help.

and here is the secound one, this one i could not do. by the way its my first yeat of C++.



"Given a set of coded information about a student, write a program that prints this information on a single line. For example,
A male student, at age 17, from Black Sea region, has fair performance with a GPA of 2.58"

Coded information is as follows:
Sex: 1:male, 2:female
Home region: 1:Marmara, 2: Agean, 3:Mediterrenian, 4:Central, :Black Sea, 6:Southeast, 7:East
Year of birth: 1988
GPA: 3-4: good, 2-2.99: fair, 1-1.99: poor, 0-0.99:failing

Well This should be in C forum not in c++...anyways here is the working code....though its printing in reverse order...make some changes yourself

Code:

---

#include <stdio.h>
 
int main()
{
 int num;
 
 printf("Enter a five-digit number:");
 scanf("%d",&num);
 
 while(num>0)
 {
        printf("%4d",num%10);
        num/=10;
 }
  return 0;
}

Ok we have a C board and a C++ board please stick to the right ones please.

i did like this:

Code:

---


#include <stdio.h>

int main()
{
        int num;
       
        printf("Enter a five-digit number:");
        scanf("%d", &num);

        printf("%d", num/10000);
        printf("  ");
        num=num%10000;
        printf("%d", num/1000);
        printf("  ");
        num=num%1000;
        printf("%d", num/100);
        printf("  ");
        num=num%100;
        printf("%d", num/10);
        printf("  ");
        num=num%10;
        printf("%d", num/1);
        printf("  \n");
        num=num%1;


                return 0;
}

and it works well, thanks for your help also.

what about second one?

i begun like this

Code:

---


#include <stdio.h>

int main()
{

        int sex,male,female,homeregion,yearofbirth,gpa;

        printf("Enter sex (1:male, 2:female:");
        scanf("%d",sex);
        if(sex==1)
                printf("male\n");
        if(sex==2)
                printf("female\n");
       
        printf("Enter home region (1:Marmara,2:Agean,3:Mediterrenian,4:Central,5:Black Sea,6:Southeast,7:East");
        scanf("%d",homeregion);
        if(homeregion==1)
                printf("Marmara\n");       
        if(homeregion==2)
                printf("Agean\n");       
        if(homeregion==3)
                printf("Mediterrenian\n");       
        if(homeregion==4)
                printf("Central\n");       
        if(homeregion==5)
                printf("Black Sea\n");       
        if(homeregion==6)
                printf("Southeast\n");       
        if(homeregion==7)
                printf("East\n");       
        if(homeregion==1)

bu i do not how to continue. could someone help guys.

prog-bman i beg your pardon, i'm new here.


*modedit nvoigt: fixed [ code ] blocks*

It compiles fine as C++ and he mentioned a C++ course so I see no reason why this should be in another board.

The code is also valid C, but that doesn't make it C only.

Well if that is the case why not just have a C++ board since well almost all C compiles as C++. It's just a waste of a board.

guys can you help me with this one?

Code:

/* Problem Statement:
Write a program that reads a nonnegative integer and computes and prints its factorial.

*/

#include <stdio.h>

int main()
{

        int num=0,numb;
        unsigned factorial=1;
       
        printf("Enter a nonnegative integer:");
        scanf("%d",numb);
       
        while(numb<0);
        numb=-1;

        while(num++<numb){
                factorial*=num==0?1:num;
        }

        printf("this numb !%d is factorial",numb);

                return 0;
}

---

its not work. help please

> while(numb<0);
Loops forever.
Hint - always use braces, even for trivial one-liner statements like you just attempted.

> factorial*=num==0?1:num;
Simplify into something more readable

Code:

---

if ( num > 0 ) factorial = factorial * num;
