C has the following simple data types:
The Pascal Equivalents are:
On UNIX systems all ints are long ints unless specified as short int explicitly.
NOTE: There is NO Boolean type in C - you should use char, int or (better) unsigned char.
Unsigned can be used with all char and int types.
To declare a variable in C, do:
var_type list variables;
e.g.
int i,j,k;
float x,y,z;
char ch;
