We can read a string using the %s conversion specification in the scanf function. However, it has a limitation that the strings entered cannot contain spaces and tabs. To overcome this problem, the C standard library provides the gets function. It allows us to read a line of characters (inc...
puts(c); c中并没有换行符,但是puts打印玩good后会默认换行,这个换行就是它自己增加的,也就是老谭所说的意思。 char *gets( char *str ); The gets() function reads characters from STDIN and loads them into str, until a newline or EOF is reached. The newline character is translated into a ...
In this article, we are going to learn about the putchar() and puts() function of stdio.h header file in C programming language and use it put string and characters on console.
C语⾔中的 puts()函数 (puts() function in C) The puts() function is defined in the <stdio.h> header file. pu ts ( ) 函数在<stdio.h>头⽂件中定义。 Prototype: 原型: int puts(const char *string); Parameters: const char *string 参数: const char * string Return type: int 返回...
Parameters str C string to be printed.Return Value On success, a non-negative value is returned. On error, the function returns EOF and sets the error indicator (ferror).Example 12345678 /* puts example : hello world! */ #include <stdio.h> int main () { char string [] = "Hello ...
The main difference between fputs() and puts() is the puts() function appends a newline character to the output, while fputs() function does not. It is defined in <cstdio> header file. puts() Parameters str: The string to be written. puts() Return value On success, the puts() func...
Firstly, let's read following simple code: in function input_number() and output_number(), printf() are called. After build, will them still be the printf()? Let's dump it. Look, in input_number(), ad...C语言中的scanf、printf 和 fprintf、fwrite 和getchar、puts、gets 和 strchr用法...
The puts() function returns EOF if an error occurs. A nonnegative return value indicates that no error has occurred.The value of errno may be set to: Value Meaning ECONVERT A conversion error occurred. EPUTANDGET An illegal write operation occurred after a read operation. EIOERROR A non...
In this chapter we will learn all the functions used on strings in C - gets(), fgets(), getline(), getdelim(), getchar(), puts(), putchar(), strlen() in C language.
