How do you store the digits of a number in an array in C?

Store each digit separately in an array

1. +8. #include using namespace std; int main() { int i = 1234; int x = i, c = 0; while(x != 0) { ++c; x /= 10; } int v = c; int j [c]; while(i != 0) { j[–c] = i \% 10; i /= 10; } for(int y = 0; y < v; y++) cout << j[y] << endl; }
2. +5.
3. +2.

How many digits can an integer store?

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. The number 2,147,483,648 is a reserved value and cannot be used. The INTEGER value is stored as a signed binary integer and is typically used to store counts, quantities, and so on.

How do you store big 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.

How do you declare a long int?

1. “long long int” is best suitable. scanf(“\%lld”,&input);
2. U can also use “unsigned long long int” if input is +ve always. scanf(“\%llu”,&input);

How do you store 4 digit numbers in an array?

To store each digit from a number into successive array location

1. void adddigits(int num)
2. {
3. int i, length, a = 0, digsum = 0, digit[] = {‘\0’};
4. while(num!=0)
5. {
6. digit[a] = num \% 10;
7. printf(“a value is: \%d, “, a);
8. printf(“digit[a] value is: \%d, “, digit[a]);

How many digits can an integer hold in C?

Standard Integers: int This means that it can store values from -32,768 to 32,767, or more depending on hardware. Like all of these other data types, there is an unsigned variant that can be used.

How are integers stored in C?

Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,294,967,295 (232 – 1) can be stored. Below are the integers 1 to 5 stored as four-byte values (each row represents one integer).

Can I use long long int in C?

You must use \%ld to print a long int , and \%lld to print a long long int . Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you’re using).

Is there long int in C?

In C, the long int data type occupies 4 bytes (32 bits) of memory to store an integer value. long int or signed long int data type denotes a 32 – bit signed integer that can hold any value between -2,147,483,648 (-2 31) and 2,147,483,647 (2 31 -1). It does not use a bit to store the sign.

Can long int store 10 digit numbers in C++?

The minimum ranges you can rely on are: This means that no, long int cannot be relied upon to store any 10 digit number. However, a larger type long long int was introduced to C in C99 and C++ in C++11 (this type is also often supported as an extension by compilers built for older standards that did not include it).

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 do you store a large integer in an array?

Storing the big integer into an integer array will help to perform some basic arithmetic on that number. Take the large number as input and store it in a string. Create an integer array arr [] of length same as the string size.

How many numbers can an unsigned long int hold on 32 bit?

Can unsigned long int hold a ten digits number (1,000,000,000 – 9,999,999,999) on a 32-bit computer. Highly active question. Earn 10 reputation (not counting the association bonus) in order to answer this question.
