Question

Check Wheather a given
digit its present in a number
or not.​

Answer 1

In order to find this you can use a loop to extract digit by digit and then check it.

for example if we have to search for the digit 8 in a number.

The following loop will do it

int num,n, digit,i;

while(num>=0)

{

n=num%10;

if(n==digit)

{

cout<<"It is present";

i++;

}

num/=10;

}

if(i==0)

cout<<"The digit is absent";

}
