C++: A PROGRAM INPUT A NUMBER AND CHECK WHEATHER PRIME OR NOT
# include<iostream.h> # include<conio.h>
//calculation int isprime(int valuex) { int x,j; x=1; & for (j=2 ; j<valuex2; j++) { if ((valuex%j)==0) x=0; } & if(x!=0) return 1; & else return 0; }
void main(){ int isprime(int); int value;
//input cout<<"Enter a number to verify whether it is prime or not "<<endl; cin>>value;
//output & if (isprime(value)==1) cout<<"Yes the number is prime"<<endl; & else cout<<"Sorry, not a prime"<<endl; & getch(); }
PROGRAM TO DO A MULTIPLICATION USING DO WHILE LOOP
# include<iostream.h> # include<conio.h>
void main(){ int a,b,ab; cout<<"Enter a first number: "<<endl; cin>>a; cout<<"Enter a second number: "<<endl; cin>>b; ab=0; while (b>0){ & ab = ab+a; & b--; & } cout<<"a*b = "<<ab; getch(); }
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
