Practice 1-14 Write a program that prints a histogram of the frequency of each character in the input.The code is as follows:#include //contains information about the standard library. intMain ()//defines a function named Main, which does not accept parameter values. {printf ("====== The histogram of the frequency of the input characters printed ======\n"); unsignedintXst -];//an array of character frequencies. intI, J, C; I= J =

Practice 1-11 How are you going to test the word count program? If there is some kind of error in the program, what kind of input is most likely to find such errors?The code is as follows:#include //contains information about the standard library. #defineIn 1/* within the word */#defineOut 0/* outside the word */intMainvoid)//defines a function named Main, which does not accept parameter values. {printf ("====== counter Program ======\n"); intC, NL, NW, NC, State; State=Out ; NL= NW = NC =0; wh

Practice 1-8 Write a program that counts the number of spaces, tabs, and line breaks.The code is as follows:#include //contains information about the standard library. intMain ()//defines a function named Main, which does not accept parameter values. {printf ("====== counts the number of spaces, tabs, and line breaks in the characters entered ======\n"); //characters entered, space-space Counter, tab counter, line break counter. intC, SL, TL, NL; SL= TL = NL =0; while((

Practice 1-16 Modify the main program of the program that prints the longest line of text, main, so that it can print the length of any length of input lines and print as much text as possible.The code is as follows:#include //contains information about the standard library. #defineMAXLINE 10intGetlineCharLine[],intmaxline);intMain ()//defines a function named Main, which does not accept parameter values. { intLen; intMax; CharLine[maxline]; while(max = Getline (line, MAXLINE)) >0) {printf (

methods are based on a single unit of code. Object-oriented programming methods allow objects to be independent. (4) One-time use and reusable comparison Depending on the implementation, the structured process may not be reused. and an object-oriented approach, an object is a modular unit. Has a complete entity, so it can be highly reusable. (5) Comparison of ordered algorithm and unordered algorithm A structured

Practice 1-1 running the "Hello, World" program in your own system. Then deliberately remove part of the program, to see what error messages will be obtained.The code is as follows:#include // contains information about the standard library. int main () // defines a function named Main, which does not accept parameter values. { printf ("Hello, world\n"); // The man function calls the library function printf to display a sequence of characters. getch (); // Prevent t

Exercise 1-15 Rewrite the temperature conversion program in section 1.2 and use the function to achieve temperature conversion calculations.The code is as follows:#include //contains information about the standard library. floatFahrtocelsius (floatFahr);floatCelsiustofahr (floatCelsius);intMain ()//defines a function named Main, which does not accept parameter values. {printf ("1 degrees Fahrenheit is equal to%.1f degrees Celsius .", Fahrtocelsius (1)); printf ("\ n"); printf ("1 degrees Celsius

Troubleshooting The data types supported by C # are: (1) Value type Includes: Simple type, struct type, enum type. Among them, the simple type is divided into: integral type, Boolean type, character type, f

As long as you have Internet browser, you can use the B/s system. However, the B/s structure of the client can only complete browsing, query, data entry and other simple functions, most of the work to be borne by the server, which put forward a very h
