What is meaning of NS in C?
Furthermore fscanf (and scanf ) will read the longest sequence of input characters matching the format. So scanf(“\%[^\n]”, s); will read all characters until you reach \n (or EOF ) and put them in s . It is a common idiom to read a whole line in C. See also §7.21. 6.2 The fscanf function.
What is the meaning of the statement scanf \%[ n s line );?
scanf(“\%[^\n]s”,a); This reads a string until user inputs a new line character, considering the white spaces also as string.
What does str mean in C?
A string in C is simply an array of characters. The following line declares an array that can hold a string of up to 99 characters. char str[100]; It holds characters as you would expect: str[0] is the first character of the string, str[1] is the second character, and so on.
What does scanf \%[ n ]\%* C exactly mean?
, B.Tech. Mechanical Engineering (2018) In short, the statement. scanf(“\%[^\n]\%*c”,name); means that all the characters entered as the input, including the spaces, until we hit the enter button are stored in the variable, name; provided we allocate sufficient memory for the variable.
What is the meaning of return 0 in C?
return 0: A return 0 means that the program will execute successfully and did what it was intended to do. return 1: A return 1 means that there is some error while executing the program and it is not performing what it was intended to do.
What is Fgets function in C?
The fgets() function in C reads up to n characters from the stream (file stream or standard input stream) to a string str . The fgets() function keeps on reading characters until: a newline character is encountered. end of file (EOF) is reached.
How do I convert a string to the same string in C++?
Assigns a new value to the string, replacing its current contents. Copies str….std::string::assign.
| string (1) | string& assign (const string& str); |
|---|---|
| buffer (4) | string& assign (const char* s, size_t n); |
| fill (5) | string& assign (size_t n, char c); |
What is the meaning of return 1 in C?
return 1 in the main function means that the program does not execute successfully and there is some error. In user-defined function. return 0 means that the user-defined function is returning false. return 1 means that the user-defined function is returning true.
How many characters does strlen(STR) contain in the given string?
Explanation: The function strlen returns the number of characters int the given string. Therefore, strlen (str) becomes strlen (“India”) contains 5 characters. A string is a collection of characters terminated by ‘\\0’. The output of the program is “5”.
What is the output of the program strlen(123456)?
Explanation: The function strlen returns the number of characters in the given string. Therefore, strlen (“123456”) returns 6. Hence the output of the program is “6”. 11.What will be the output of the program?
What does the expression [fun()+ printf (“I See You”)] Mean?
The expression [fun ()+ printf (“I see you”)] can be boiled down to [“awake” + 9] which is nothing but base address of string literal 3awake ́ displaced by 9 characters. Hence, the expression [“awake” + 9] returns junk data when printed via \%s specifier till it finds μ\\0 .
What is the difference between \%s and \%WS in scanf()?
In general scanf () function with format specification like \%s and specification with the field width in the form of \%ws can read-only strings till non-whitespace part. It means they cannot be used for reading a text containing more than one word, especially with Whitespaces. Table of difference and similarities between gets () and \% n]
