How do you store large numbers?
Take the large number as input and store it in a string. Create an integer array arr[] of length same as the string size. Iterate over all characters (digits) of string str one by one and store that digits in the corresponding index of the array arr.
Can long long int store 10 18?
You can use a long long to store this integer. A long long is guranteed to hold at least 64 bits. The problem with this code: if( a>=0 && a <= (1000000000000000000)) is that you need to give the literal ( 1000000000000000000 ) the suffix LL if you want it to be of type long long or ULL for unsigned long long .
Can int store 10 digits?
The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. If a data value lies outside the numeric range of INTEGER, the database server does not store the value.

How can I store 10100 as an integer in C++?
No data type is present in C++ to store 10100. So, the idea is to use get the input as string (as string can be of any length) and then convert this string into an array of digits of the length same as the length of string. Storing the big integer into an integer array will help to perform some basic arithmetic on that number.
How can I write a 100 digit integer in C?
C doesn’t have any inbuilt data type to store 100 digit numbers. You simply use an array of integers and perform the arithmetic operations manually! I’m sure you will find a good big integer library for C, if you need it for a real world project.
