How do you get the length of a number in C++?
int size = trunc(log10(num)) + 1 …. If you can use C libraries then one method would be to use sprintf, e.g. For an int type of 4 bytes, the result is 11. An example of 4 bytes int with 11 decimal digits is: “-2147483648”.
How do you find the first digit of an integer?
To find first digit of a number we divide the given number by 10 until number is greater than 10. At the end we are left with the first digit.

How big is an integer?
The size of a signed or unsigned int item is the standard size of an integer on a particular machine. For example, in 16-bit operating systems, the int type is usually 16 bits, or 2 bytes. In 32-bit operating systems, the int type is usually 32 bits, or 4 bytes.
What is the differerence between integer and long?
The int data type is a 32-bit signed two’s complement integer. The long data type is a 64-bit signed two’s complement integer. The long is a larger data type than int. The difference between int and long is that int is 32 bits in width while long is 64 bits in width .
