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):70 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!
