C One Dimensional Array

What is One Dimensional Array ?

An Array which has only one subscript is known as One Dimensional Array.

i.e. int arr[10].

Syntax :-

Data_type Variable_name[Size];

Rules For Declaring One Dimensional Array :

1: An Array variable must be declared before being used in Program.

2: The declaration must have a datatype (int , float , char , double , etc..), variable name , subscript.

3: The subscript represents the size of the Array. if the size if 5 , we can store 5 elements.

4: An Array index always starts from 0.

If an array variable is declared as arr[15] , then it range from 0 to 14.

5: Each array elements stored in separate memory location.

In C-language an Array variable is also initialize without mentioning the size of an Array.

Declaration :-

1 : int Salary[5] = { 10000 , 12000 , 12300 , 20000 , 21000 };

2 : int Salary[] = { 10000 , 12000 , 12300 , 20000 , 21000 };

PROGRAM :-

#include<stdio.h>

void main()
{
int Salary[5];
int i,n=5;

//Input the Salaries
printf("Enter 5 Salaries\n");
for(i=0;i<n;i++){
scanf("%d",&Salary[i]);
}

// printing the All salaries
printf("\n<---Salaries--->\n");

for(i=0;i<n;i++){
printf(" Salary %d = %d\n", i+1, Salary[i]);
}
}

OUTPUT :-

Enter 5 Salaries

10000

12000

12300

20000

21000

<- - - Salaries - - ->

Salary 1 = 10000

Salary 2 = 12000

Salary 3 = 12300

Salary 4 = 20000

Salary 5 = 21000
