C LANGUAGE PART 5

Simple program to add two numbers in c programming.


#include <stdio.h>
#include <conio.h>
int main()
{
  int number1, number2, sum;
  printf("Enter two integers: ");
  scanf("%d %d", &number1, &number2);
  sum = number1 + number2;
  printf("%d + %d = %d", number1, number2, sum);
  return 0;
}

Integer Datatype

An integer is a whole number that can be positive, negative, or zero.

Data Type	Memory	Range	Format Specifier
short int	2	-32768 to 32767	%hd
unsigned short int	2	0 to 65535	%hu
unsigned int	4	0 to 4294967295	%u
int	4	-2147483648 to 2147483647	%d
long int	4	-2147483648 to 2147483647	%ld
unsigned long int	4	0 to 4294967295	%lu
long long int	8	-9223372036854775808 To 9223372036854775807	%lld
unsigned long long int	8	0 to 18446744073709551615	%llu

Character Data Type in C Programming

Character is a data type that holds one character (letter, number, etc.) of data. It must be enclosed with single quotes. e.g. 'A', '4', or '#'

Data Type	Memory	Range	Format Specifier
char or signed char	1	-128 to 127	%c
unsigned char	1	0 to 255	%c

Floating Point Data Type in C Programming

Float is a shortened term for floating point.
