variable define in c code example
Example 1: declare variable in c
int i, j, k;
char c, ch;
float f, salary;
double d;
Example 2: declaring variables in c
// First declaring and then initializing
int a;
int a = 5;
// Declaring and initializing at one time
int b = 6;
// Basically used datatypes
// 1. int // integer
int num = 2;
// 2. float // decimal number
float number = 234.87;
// 3. char // character
char ch = 'p';
// 4. char[] // string
char name[] = {'B','i', 'l','l'}
// or
char fav_fruit[] = "apple"
Example 3: c how to define a variable
int age; //int variableName; or int variableName = Value;
//Integers are whole numbers: 2, 23. They are NOT: 28.4, 8.07.
char first_initial; //char variableName; or char variableName = 'Character';
//Characters are single characters on the keyboard. Numbers can
//be characters but they are best not stored as such
char name[10]; //char stringName[size] or char stringName[size] = "String"
//Strings are defined as an array of characters that end
//w/a special character ‘\0’.
float salary; //float variableName; or float variableName = value;
//Floats are numbers that contain up to seven digits including decimals.
double micro; //double variableName; or double variableName = value;
//Doubles are more precise than floats and can hold more numbers.
