Data Types in C

Primitive Data Types in C:

1. int

2. float

3. char

4. double

5. void

Derived Data Types in C:

1. array

2. pointer

3. function

User-Defined Data Types in C:

1. structure

2. union

3. enum

#include<stdio.h>

#include<stdbool.h>

// extern variable declaration

extern int x;

int main()

{

int age = 30;

char name[] = "Embedded";

float average = 66.78;

char gender = 'M';

bool result = true;

printf("extern integer Data : %d\n",x);

printf("Integer Data : %d\n", age);

printf("String Data : %s\n", name);

printf("Float Data : %f\n", average);

printf("Character Data : %c\n", gender);

printf("Boolean Data in integer form : %d\n", result);

printf("size of int is = %u\n", sizeof(int));

printf("size of char is=%u\n", sizeof(char));

printf("size of float is=%u\n", sizeof(float));

printf("size of bool is=%u\n", sizeof(bool));

return 0;

}

int x=5; // use of extern variable at different location
