Piotrowski & Brendan MortGeneral:#include <file.h>or #include "file.h"places the contents of file.h into the current files and allows functions from file.h to be used in your program. NOTE:<> are used for standard C libraries while "" are used for usercreated header files. You will most likely only requirethe standard C library file <stdio.h> in your programs.int main() {...return 0;}This function is needed in all C programs. The body of your code replaces the ellipses. return 0 signifies that theprogram has completed successfully and should end.Variable Types:int integer value from 2147483648 to 2147483647NOTE: The usual values range from 32768 to 32767float real value accurate to 8 decimal places.double real value accurate to 17 decimal places.Arrays:Declaring an array:type variablen];type can be any of the above variable types.variable is the name of the array.n is the number of elements you want to have in the array.Accessing an array:variableindex]This accesses the value stored in the array at the index. The index is an integer from 0 to n1.Example:int my_array10];my_array0]=73;my_array9]=my_ar ray0];Page 2This segment of code creates an array called my_array with a size of 10. The value of the array at index 0 which isthe first element in the array is set to 73. The value of the array at index 9 which is the last element in the array isthen set to the value of the array at index 0.Input/Output:printf("Hello");o rprintf("Hello %d" x);This statement writes to the standard output. NOTE: %d is a control character that is replaced by a variable of thesame type. The control characters are:%d for int%f for float%lf for doubleIn the above example x is a variable of type int.scanf("%d %f" &x &y);This statement reads values from the standard input (by default the keyboard) and stores them to a variable ...
