Take an example snippet in c++
int a,b,c;
cin >>a>>b;
c=a*b;
cout<<c;
For small numbers this is just a snippet to multiply 2 numbers
But if
a=100000000
b=1000000000000000000
Then this code don’t give the desired output
Because the product of the numbers crosses the range of int data type
How to fix this issue so taht for any two numbers till infinity also we can find product
Can you help me sort out this issue …
