C Arrays

Arrays, used to store multiple values in a single variable

To create an array, define the data type and specify the name of the array followed by square brackets [].

To insert values to it, use a comma-separated list, inside curly braces:

int myNumbers [] = {25, 50, 75, 100};

To access an arrelement, refer to its index number. Array indexes start with 0. myNumbers[0] refers to 25.

Code:

  #include 
  int main() {
  int myNumbers[] = {25, 50, 75, 100};
  printf("%d", myNumbers[0]);
  return 0;
  }

Output

Explanation

Declare integer Array named myNumbers and store {25, 50, 75 100} to it (By using the syntax: type arrayName = {value1, value2, ……};).

To output first value of array, use format specifiers %d because here array contains integers.

You can change the value of a specific element, refer to the index number:

myNumbers [0]=33

• Now myNumbers[0] refers to 33.
