The getchar() is used in 'C' programming language because it can read the character from the Standard input(i.e..from the user keyboard),and converts in to the ASCII value.

What is the purpose of a getchar function?
The getchar() function gets a single character from stdin. Here is a very basic example: #include <stdio.h> int main() { char ch; do { ch = getchar(); putchar(ch); } while (ch != ';'); return 0; } It reads from data you input and prints it again of the screen after you press key. It works until it reaches ";" symbol. The getchar() function is equivalent to getc(stdin).
What is the use of getchar?
gets()Reads characters from stdin and stores them as a string into str until a newline character ('\n') or the End-of-File is reached.The ending newline character ('\n') is not included in the string.getchar()Returns the next character from the standard input (stdin).It is equivalent to getc with stdin as its argument. === ===
Why wont your c plus plus program stay open?
If you are talking about the program executing, but the output screen being displayed for a flash and then disappearing, I suggest adding getch() or getchar() function at the end of your main function. This will make sure that the output screen waits for you to press a character before the program terminates.
How do you read a character from the keyboard and will store it in the variable?
Use the scanf() function from the C standard library.
Give an example of how getchar function is used in C program.?
The getchar() function is used to read a single character from standard input (stdin) and increment the associated file pointer to point to the next character. The return value is an integer which must be cast to a character. An example demonstrating its usage is shown below. #include <stdio.h> int main() { char buffer[81]; int i, ch; for(i=0; (i<80) && ((ch = getchar()) != EOF) && (ch!='\n'); ++i) { buffer[i] = (char) ch; // cast input to a character } buffer[i] = '\0'; // add null-terminator. printf( "You entered: %s\n", buffer); }

if you do not used main function in c program when errors are accrued

Can you use getchar instead of scanf in a c program?
They do different things, read the manual/help for details.

How Can We Solve The Limitation Of Getchar And Scan Function?
Getchar:-Reading a single character can be done by using the function getchar.Syntax:- variable_name = getchar ( );Variable_name is a valid 'c' name that has been declared as char type. When this statement is encountered, the computer waits until a key is pressed and then assigns this character as a value to getchar function. Since getchar is used on the right hand side of an assignment statement, the character value of getchar is in turn assigned to the variable_name on the left. The getchar function may be called successively to read the characters contained in a line of text. Getchar accepts space character.Scanf ("control strings",arg1, arg2, ………… argn);The control string specifies the field format in which the data is to be entered and the arguments arg 1, arg 2, arg n specify the address of locations where the data is stored. Scanf does not accept space character.
What is function get in C programming?
There is no 'get' in the standard libraries, but for 'getc', 'getch', 'getchar', 'fgetc' etc you can find useful information in the help/manual.
What function enables the user to input information while the program is being executed in c?
The scanf() function is a commonly used function to input information during the execution of a program. scanf() function has its prototype in the stdio.h header file. To accept and display a number: int num; printf("Enter a number: "); scanf("%d",&num); printf("You entered %d",num); To accept and display a character, replace %d with %c and make num a character variable [char]. Plus: gets, fgets, read, fread, getchar, getc, fgetc, getch...
What c code would allow the c library that includes the log function to be used in a program?
01
Is that any other way to input data in c language other than scanf function?
read, fread, gets, fgets, getc, fgetc, getchar, getch
