This document discusses C programming tokens, data types, operators, input/output functions, and control structures. It covers basic C concepts like keywords, constants, variables, arithmetic, relational, and logical operators. It also outlines different data types like integer, floating point, character, and their hierarchies. Common control structures like if-else, switch, while, do-while, for loops and decision making statements are summarized as well.

Operations
 Reading a character
variabl_name = getchar();
 Writing a character
putchar(variable-name);
 Formatted input
scanf(“control string”,arg1,arg2,….,arg n);
 Formatted output
printf(“control string”, arg1,arg2, ….,arg n);

12. Decision Making and Looping
 THEWHILE STATEMENT
while(test condition)
{
body of the loop
}

 THE FOR STATEMENT
for(initialization; test-condition; increment)
{
body of the loop
}
