Array Ist tutorial

1.WAP to accept rollno of 5 students and display them.
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
double a[5],i;
cout<<"\t\t\t\t\tLaxman"<<endl;
cout<<"Enter the Roll No4."<<endl;
for(i=0;i<=4;i++){
cin>>a[i];
}
for(i=0;i<=4;i++)
{
cout<<a[i]<<endl;
}
getch();}
2. WAP to accept 5 no and reverse them.
#include<iostream.h>
#include<conio.h>
void main(){
clrscr();
int a[5],i;
cout<<"\t\t\t\tLaxman"<<endl;
cout<<"Enter the No."<<endl;
for(i=0;i<=4;i++)
{
cin>>a[i];
}
cout<<"Reverse of No."<<endl;
for(i=4;i>=0;i--)
{
cout<<a[i]<<endl;
}
getch();
}

3. WAP to accept 10 integer and find the sum of all even and odd numbers separately.
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
cout<<" \t\t\t\tLaxman"<<endl;
int a[10],i,sume=0,sumo=0;
cout<<"Enter the no."<<endl;
for(i=0;i<=9;i++)
{
cin>>a[i];
}
for(i=0;i<=9;i++)
{
if(a[i]%2==0)
sume=sume+a[i];
else
sumo=sumo+a[i];
}
cout<<"Sum of Even No."<<sume<<endl;
cout<<"Sum of Odd No."<<sumo;
getch();
}
4.WAP to accept 10 element and identify the max and min no in the array also identify the position as well.
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
cout<<" \t\t\t\tLaxman"<<endl;
int a[10],i,max=0,min=0,m,n;
cout<<"Enter the no."<<endl;
for(i=0;i<=9;i++)
{
cin>>a[i];
}
for(i=0;i<=9;i++)
{
if(max<a[i])
{
max=a[i];
m=i;
}
else if(min>a[i])
{
min=a[i];
n=i;
}}
cout<<"Maximum no.is"<<max;
cout<<"\t& Position of max.is"<<m+1<<endl;
cout<<"Minimum no.is"<<min;
cout<<"\t& Position of min.is"<<n+1;
getch();
}
5. WAP to accept the amount of sale made for each day in a week and calculate the average of these values.
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
cout<<" \t\t\t\tLaxman"<<endl;
int a[7],i,j=0;
cout<<"Enter the sales"<<endl;
for(i=0;i<7;i++)
{
cout<<"Day "<<i+1<<"\t\t";
cin>>a[i];
j+=a[i];
}
cout<<"The sales for week"<<j;

getch();

}
