Hello,
I have an assignment, which is almost done, but I'm completely stocked on one little thing.
this is what i need to do:
The program shuld take from the user the class/subject names and for each class, the number
of hours, a student has to attend in one week, together with the number of hours, the student
has missed for each class. The program should then display a nicely laid out table of the classes
with their related number of hours and the missed number of hours. The program should also tell
the user, how many hours she/he has to perform self-study for each subject/class and the total
hours of his/her needed for self-study for that week to catch up with her/his studies, with the
idea in mind, that each missed class hour is equal to two hours of self study.
Assumptions: a student doesn't have the same class twice a week; a student has a minimum of 3 classes in a week;
And that's what I have:
CODE
#include<iostream.h>
#include <stdio.h>
#include <cstring.h>
int main()
{
unsigned int i,j,amount_classes, hours[10], missed[10], self_study[20];
unsigned int self_total;
char str[70][40], name[40];
cout<<"Please enter your name: "<<endl;
gets(name);
cout<<"Please enter how many classes you have per week: "<<endl;
cin>>amount_classes;
if (amount_classes<3)
{
cout<<"You can't have less than 3 classes a week!";
return 0;
}
else
{
for (i=1; i<=amount_classes; i++)
{
cout<<"Please enter the name of "<<i<<" subject: "<<endl;
gets(str[i]);
for (j=1;j<=i-1;j++)
if (!strcmp(str[i],str[j]))
{cout<<"You've entered same subject twice!"<<endl;
return 0;
}
cout<<"How many hours per week do you have for this class? "<<endl;
{cin>>hours[i];
if (hours[i]>168)
{cout<<"This is impossible! There is 168 hours in a week! "; return 0;}}
cout<<"And how many did you miss this week? :"<<endl;
cin>>missed[i];
self_study[i]=missed[i]*2;
if (missed>hours)
{cout<<"You can't miss more hours than it should be per week!";
return 0;
}
}
self_total=0;
for (i=1;i<=amount_classes;i++)
self_total=self_total+self_study[i];
for (i=1;i<=amount_classes;i++)
{
cout<<strlen(str[i])<<endl;
for (j=strlen(str[i]);j<25;j++)
str[i][j]='*';
}
for (i=0; name[i]; i++)
name[i]=toupper(name[i]);
cout<<endl<<name<<": "<<endl;
for (i=1;i<=amount_classes; i++)
{
cout<<endl<<str[i]<<hours[i];
if (hours[i]>=10)
cout<<"*****"<<missed[i];
else
cout<<"******"<<missed[i];
cout<<"______"<<self_study[i]<<" ";
cout<<strlen(str[i]);
}
cout<<"\nTotally this week you need to study "<<self_total<<" hours."<<endl;
}
cin.get();
cin.get();
}
The problem is when i'm trying to do thos table, it gives me some strange symbols at the end, and the length of a string is bigger than it should be. Whan i change it, it still gives me different kind of results, with this strange symbols.
Mod Edit: Please use code tags:
To use them properly you would type something like:
[code]//Your code goes here
#include <stdio.h>
int main() {
printf("Hello World");
return 0;
}
[/code]
