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 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%
