Use of 'static' keyword for functions
19. Writing functions and testing those functions
Students should be able to write any function according to the given description. Lot of students used to write only main() function. They are not comfortable in writing a separate function and calling that function from main function. But important skill is to write to given function with given description. One should be able to call this function from main() function and should be able to test that function.
20. Understanding and using following C library functions
Standard Input/Output Functions
putchar(); puts(); printf(); getchar(); gets(); scanf();
String Functions
strlen(); strcpy(); strncpy(); strcat(); strncat(); strcmp(); strncmp(); memcpy(); memcmp();
Character class testing and Conversion functions
isalpha(); isupper(); islower(); isdigit(); isalnum(); isspace(); toupper(); tolower();
Storage management functions
malloc(); calloc(); free();
Math functions
