## How do you read a set of numbers in C?

Steps:

1. Define a function max()
2. Under main() function, declare two integers i and n.
3. Declare an array a.
4. Prompt the message to the user to insert how many elements they want to enter using printf() and allow to enter using scanf().
5. Prompt the message and allow to enter the elements.

Which data type can hold 10 digit integer numbers in C?

Basic data types in C language:

• 1.1. Integer data type:
• 1.2. Character data type:
• 1.3. Floating point data type:
• float: Float data type allows a variable to store decimal values.
• double: Double data type is also same as float data type which allows up-to 10 digits after decimal.
• 1.3.
• 1.3.
• ### Which data type is used when data to be entered has large number of digits?

Approximate types include floating point data types. The decimal data type is an exact numeric data type defined by its precision (total number of digits) and scale (number of digits to the right of the decimal point).

How many digits does a long store?

long: The long data type is a 64-bit two’s complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.

## What is real number in C language?

Real numbers are represented in C by the floating point types float, double, and long double. Just as the integer types can’t represent all integers because they fit in a bounded number of bytes, so also the floating-point types can’t represent all real numbers.

What is the EOF in C?

The End of the File (EOF) indicates the end of input. After we enter the text, if we press ctrl+Z, the text terminates i.e. it indicates the file reached end nothing to read.

### What is integer in C language?

What are the basic data types supported by C language?

Main types. The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long.

## Should it be string or int?

5 Answers. You are doing the right thing – identity field should be numeric and not string based, both for space saving and for performance reasons (matching keys on strings is slower than matching on integers).

Which numeric data type has largest range?

Explanation: Longtext has largest range.

### How big is a long in C?

8 bytes
Integer Types

Type Storage size Value range
short 2 bytes -32,768 to 32,767
unsigned short 2 bytes 0 to 65,535
long 8 bytes or (4bytes for 32 bit OS) -9223372036854775808 to 9223372036854775807
unsigned long 8 bytes 0 to 18446744073709551615

What is double coding?

The double is a fundamental data type built into the compiler and used to define numeric variables holding numbers with decimal points. A double type can represent fractional as well as whole values. It can contain up to 15 digits in total, including those before and after the decimal point.

## How to find first digit of a number in C program?

And then, it is going to find the First Digit of the user entered value. Within this C Program to Find First Digit Of a Number, User entered Value : Number = 1234 FirstDigit = 1234 / pow (10, 3) = 1234 / 1000 = 1.234 = 1
