Write a c++ program to multiply two numbers without using multiplication operator.
#include<iostream.h> #include<conio.h> void main () { int a,b,i,temp=0; clrscr(); cout<<"Enter Two numbers for multiplication"; cin>>a>>b; for(i=1;i<=b;i++) { temp=temp+a; } cout<<endl<<"Result are:: "<<temp; getch(); } |

It will not work
1.If a is -ve
2.b is -ve
#include
#include
{
clrscr();
int a,b,c;
cout<>a>>b;
c=a*b;
cout<<"The answer is: "<<c;
getch();
}
Hi,
just update the For loop condition
#include
#include
void main ()
{
int a,b,i,temp=0;
clrscr();
cout<>a>>b;
for(i=1;i<b;i++)
{
temp=temp+a;
}
cout<<endl<<"Result are:: "<<temp;
getch();
}
also
for(i=0;i<=a;i+)
{
for(j=0;j<=b;j++)
{
count++;
}
}
printf("%d",count);
while loop?
I really like reading through a post that will make people think.
Also, many thanks for allowing for me to comment!
