Review

• C Language Features

– control flow

– C operators

– program structure

– data types

– I/O and files

• Problem Solving Abilities

Control flow

• Looping with while, for,

do-while

• conditional execution with

if, if-else, switch

• jumps with break,

continue, goto

Control flow

for(j = 0, j < 10; ++j) { . . . }

if ( x < 0 ) { . . . } else { . . .}

C Operators

• Meaning of the various

operators and their

precedence and association.

• What are ++, --, &&,

||, !, ~, &, ^, |, =,

==, !=, <, >, >>, <<,

+=, &=, *, ->, ., ? :,

sizeof, etc

Program Structure

• main() and function, function

prototype declaration,

function definition, argument

passing, call by value vs call

by reference.

• Auto, extern, static storage

classes

• Use of standard library

functions, especially I/O

functions.

Program Structure

#include <stdio.h>

int g = 0;

char f(int x);

main()

{

char c;

c = f(5);

. . .

}

char f(int x)

{

. . .

}

Data Types

• Simple data types - int,

char, float, double

• Array, pointer, equivalence

between array syntax and

pointer syntax

• User defined types -

structure, typedef

Data Types

main()

{

int x, y, *p;

char s[100];

struct str {

float u;

float v;

int *pt;

} a, b, c;

. . .

}

Others

• Macros, #define, #if, etc

• Open and close files

• Dynamic memory allocation, malloc(), calloc()

• Internal representations of integers

• Type casts

Problem Solving

• The ability of solving a

problem by computation

through a computer program

(efficiently)

Final Exam

• Last for 2 hours

• 5 to 6 problems with varied weights

• Problems similar to tutorials and labs

• Requirement of memorization is minimal

• Overall weights, midterm and quizzes 20%, labs 20%, final 60%
