1. (6) Given the following code, set the year for today's date to 1991. struct date { int month; int day; int year; }; struct date todays_date; todays_date.year = 1991; 2. (6) Write the code to call a function named 'number_of_days' passing today's date from Problem #1 above as an argument. number_of_days( todays_date ); 3. (6) Initialize a date structure (that has the format given in Problem #1) called 'tomorrows_date' with the date July 4th, 1776. static struct date tomorrows_date = { 7, 4, 1776 }; or static struct date tomorrows_date; tomorrows_date.month = 7; tomorrows_date.day = 4; tomorrows_date.year = 1776; 4. (10) Using the date structure from Problem #1, declare a date structure with twelve birthdays and set the month of the fifth entry to twelve. struct date birthdays[12]; birthdays[4].month = 12; 5. (10) Code a structure called 'date_time' containing a date structure and a time structure as its members. struct date_time { struct date sdate; struct time stime; }; 6. (10) Code a structure called 'employee' containing a social security number and a twenty character name as its members. struct employee { long int ssn; char name[20]; }; 7. (6) Given the following code and using the code from Problem #6, set the first character of the name to R. struct employee payroll_rec; payroll_rec.name[0] = 'R'; 8. (6) Rewrite the following code using a character string: static char word [] = {'H','e','l','l','o','!','\0'}; static char word[] = {"Hello!"}; 9. (6) Code a statement to display the following: Single quotes (') and backslash (\) are special. printf("Single quotes (\') and backslash (\\) are special.\n"); 10. (6) Given the following information, convert the character '5' to the number 5 using integer arithmetic. (ASCII values for the characters '0' through '9' are 48 through 57 respectively). int i; char c = '5'; i = c - '0'; or i = c - 48; 11. (10) Write the code needed to read from a file. #includeFILE *file_ptr; file_ptr = fopen("file_name", "r"); 12. (18) Match the function with its purpose. _A___fprintf A. Writes to a file instead of a terminal. _B___fscanf B. Reads from a file instead of a terminal. _C___fopen C. Initializes a file for I/O operations. _D___fclose D. Tells the system that a file is no longer needed to be accessed. _E___feof E. Tests for an end of file condition. _F___fgets F. Reads entire lines of data from a file. _G___fputs G. Writes entire lines of data to a file. _H___getc H. Reads a single character from a file. _I___putc I. Writes a single character to a file. J. Reads a single character from a terminal. K. Writes a single character to a terminal.
