Take a break and have a look at these problems!
Problem 1: Write a Program in C++ to print the following pattern.
Example:
**********
********
******
****
**
Solution:
// Example Program in C++ // to print a pattern // that looks like a reverse // pyramid of '*' #include<iostream.h> void main(void) { int i,j,k; for(i=0;i<=10;i++) { for(j=5;j<i+5;j++) cout<<" "; for(j=5;j>i;j--) cout<<"*"; for(j=5;j>i;j--) cout<<"*"; cout<<endl; } }
Problem 2: Write a program in C++ to find the row sum and column sum of a two dimensional array. Example:
1 2 3 = 6
4 5 6 = 15
7 8 9 = 24
12 15 18
Solution:
// Example Program in c++ to find the // row sum and column sum of a 2 // dimensional array #include<iostream.h> void main(void) { int arr[3][3]={1,2,3,4,5,6,7,8,9}; int row_sum[3], col_sum[3]; int i,j; for(i=0;i<3;i++) { row_sum[i]=0; for(j=0;j<3;j++) row_sum[i]+=arr[i][j]; } for(i=0;i<3;i++) { col_sum[i]=0; for(j=0;j<3;j++) col_sum[i]+=arr[j][i]; } for(i=0;i<3;i++) { for(j=0;j<3;j++) cout<<" "<<arr[i][j]<<" "; cout<<"= "<<row_sum[i]; cout<<endl; } cout<<" \n\n"; for(i=0;i<3;i++) cout<<col_sum[i]<<" "; cout<<"\n\n"; }
Problem 3: Write a Program in C++ to find the fibonacci series (in fibonacci series every term is the sum of its preceeding two terms).
Example:
Enter No. of elements(>3):7 0 1 1 2 3 5 8
Solution:
// Example program in C++ to
// print the fibonacci series
#include<iostream.h>
void main(void)
{
int first=0,second=1,third;
int element,i;
cout<<"Enter No. of elements(>3):";
cin>>element;
cout<<"\n\n";
cout<<first<<" "<<second;
for(i=2;i<element;i++)
{
third=first+second;
cout<<" "<<third;
first=second;
second=third;
}
cout<<"\n\n";
}
Good-Bye!
