Program to Reverse Number in C

Loops

Here you will learn how to reverse number in C. #include<stdio.h> int main() { long n,rev=0,d; printf(“Enter any number:”); scanf(“%ld”,&n); while(n!=0) { d=n%10; rev=(rev*10)+d; n=n/10; } printf(“The reversed number is %ld”,rev); return 0; }   Output Enter any number:16789 The reversed number is 98761

Program to Reverse Number in C++

Loops

Here you will get program to reverse number in C++. #include<iostream> using namespace std; int main() { long n,rev=0,d; cout<<“Enter any number:”; cin>>n; while(n!=0) { d=n%10; rev=(rev*10)+d; n=n/10; } cout<<“The reversed number is “<<rev; return 0; }   Output Enter any number:12674 The reversed number is 47621

C++ program to print the following pattern:

Print Figures

#include<iostream.h>#include<conio.h>void main(){ clrscr(); //to clear the screen int i,j,k,n; cout<<“How many lines?”; cin>>n; n*=2; for(i=0;i<n;i+=2) { cout<<“n”; for(j=n;j>i;j-=2) cout<<” “; for(k=0;k<=i;++k) cout<<“*”; } getch(); //to stop the screen}

C++ program to print the following design:

Print Figures

#include<iostream.h>#include<conio.h>void main(){ clrscr(); //to clear the screen int i,j,k,n;  cout<<“How many lines?”; cin>>n;  n*=2; for(i=0;i<n;i+=2) { cout<<“n”; for(j=1;j<i;j+=2) cout<<” “; for(k=n-1;k>i;–k) cout<<“*”; } getch(); //to stop the screen}

Matrix Multiplication in C

Array

Here is the program for matrix multiplication in C. m and n are rows and columns of first matrix. p and q are rows and columns of second matrix. Then, multiplication is possible only if n==p.   Matrix Multiplication in C #include<stdio.h> int main() { int a[5][5],b[5][5],c[5][5],m,n,p,q,i,j,k; printf(“Enter rows and columns of first matrix:”); scanf(“%d%d”,&m,&n); …
