What is the syntax of scanf?
scanf: scanf is a built-in function to read input from the user.
What is scanF function?
scanf() is an input function which reads input from the standard input devices such as keyboard. Syntax: scanf("Control Character",address_list); where control character is a sequence of one or more character such as %d,%f,%lf,%lld. Address list specifies the variables, pointers etc. e.g. scanf("%d",&num);
How do you give input at run time in c?
Usually by using the scanf function
What is the use of scanf function in c?
Hiii,scanf() is an predefined function of C to getting runtime input from the user.Syntax:-scanf("sequence specifier",&variable_name);example:-#includevoid main(){int number;printf("\n Enter any number"); //message to userscanf("%d",&number); //getting input from userprintf("\n entered number is %d",number); // displaygetch();}
Difference between cin and scanf?
the getchar function waits the user hit a key followed by return key. Upon the return key hitted by the user the function returns the key. But the scanf can be used for various & different user entered data including text, integer, float and so on. in spite of getchar the delimeter keys for scanf function are tab, space and return key; so when a space entered by the user in the input the scanf will end the input and waits user enter the return key. You must take in mind that just the fragment of input that is behind these delimeters will be considered as legal input for the scanf and the remaninder will be escaped.

Printf prints something to the standard output stream, and scanf inputs something from the standard input stream.

Why you use scanf?
scanf is a function that reads data with specified format from a given string stream source, originated from C programming language, and is present in many other programming languages.The scanf function prototype is:int scanf(const char *format, ...);The function returns the total number of items successfully matched, which can be less than the number requested. If the input stream is exhausted or reading from it otherwise fails before any items are matched, EOF is returned.So far as is traceable, "scanf" stands for "scan format", because it scans the input for valid tokens and parses them according to a specified format.UsageThe scanf function is found in C, in which it reads input for numbers and other datatypes from standard input (often a command line interface or similar kind of a text user interface).The following shows code in C that reads a variable number of unformatted decimal integers from the console and prints out each of them on a separate line:#include intmain(void){int n;while (scanf("%d", &n) 1)puts(word);return 0;}No matter what the datatype the programmer wants the program to read, the arguments (such as &nabove) must be pointers pointing to memory. Otherwise, the function will not perform correctly because it will be attempting to overwrite the wrong sections of memory, rather than pointing to the memory location of the variable you are attempting to get input for.As scanf is designated to read only from standard input, many programming languages with interfaces, such as PHP, have derivatives such as sscanfand fscanf but not scanf itself.

What is standard library function in c?
The Standard Librarary Function in C is printf,scanf inf Standard input output header.. which is stdio.h.
Why do you use scanf in c?
To read input from standard input.
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...
Can you use scanf function within printf function?
Yes: double d; printf ("scanf's just returned %d\n", scanf ("%lf", &d));
Why not use the ampression symbol in scanf statement in function?
scanf is a function, not a statement. Example: int a; char name[12]; scanf ("%d %s", &a, &name[0]);
