Practice 1-7 Writing a program that prints the values of EOF.#include // contains information about the standard library. int main () // defines a function named Main, which does not accept parameter values. { // output EOF. printf ("EOF" corresponds to the number of shapes is%d.) \ n", EOF); Getch (); // Prevent the console from flashing through, you need to accept any characters after you close the console. return0; // returns a shape to the execut

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

Practice 1-18 Write a program that removes spaces and tabs at the end of each input line and removes rows that are completely blank.The code is as follows:#include //contains information about the standard library. #defineMAXLINE 10//the maximum number of characters per line is 1000. intGetlineCharLine[],intmaxline);intMain ()//defines a function named Main, which does not accept parameter values. { intLen; inti; CharLine[maxline]; while(len = getline (line, MAXLINE)) >0) { intc =

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

Practice 1-6 Verify that the value of the expression GetChar ()! = EOF is 0 or 1.The code is as follows:#include //contains information about the standard library. intMain ()//defines a function named Main, which does not accept parameter values. { //Verify that the value of GetChar ()! = EOF is 0 or 1. printf"Verify that the value of GetChar ()! = EOF is 0 or 1. \ n"); printf ("the validation is complete and the result is%d. \ n", GetChar ()! =EOF); Getch (); //prevent the console from fl

Exercise 1-22 writes a program that "folds" the longer input lines into shorter two or more lines, after the last non-whitespace before the nth column of the input row. Ensure that the program intelligently handles input lines that are long and that there are no spaces or tabs in front of the columns you have set.The code is as follows:#include //contains information about the standard library. #defineMAXLINE 1000//the maximum number of characters per line is 1000. #defineBR 10//10 characters in

; for(i =0; I 1 (c = GetChar ())! = EOF c! ='\ n';) { if(c = ='\ t') { //If you enter a tab, the following algorithm is used to calculate how many spaces are required to fill. intj =0; J= detab-i%Detab; while(J >0) {s[i++] =' '; J--; } } Else if(c = ='\ n') {s[i++] =C; } Elses[i++] =C; } S[i]=' /'; returni;}Personal Understanding:Apply n as a symbolic constant to the global benefit of uniform modification of the program, with the number of sp

Exercise 1-19 writes the function reverse (s), reversing the order of characters in the string s. Use this function to write a program that reverses the order of characters in one input line at a time.The code is as follows:#include //contains information about the standard library. #defineMAXLINE 10//the maximum number of characters per line is 1000. intGetlineCharLine[],intmaxline);voidReverseCharLine[],intlen);intMain ()//defines a function named Main, which does not accept parameter values.
