#include <stdio.h>int main() {char str[20];printf("Enter a string with spaces: ");scanf("%s", str); // 在遇到空格时停止读取printf("You entered: %s\n", str);return 0;} 在这个示例中,scanf 遇到空格就会停止读取,导致只能读取第一个单词。 代码结果: Enter a string with spaces: Hello...
scanf以删除的方式从缓冲区读入数据(来自标准输入设备的数据存储在缓冲区),也就是说,scanf从缓冲区读入一个数据项,该数据项在缓冲区中就被清除掉了。 而如果scanf需要读取一个数据项,返现缓冲区当前是空的,那么程序就会在scanf代码处阻塞,等待用户输入,scanf函数接收到相应的数据项之后,在缓冲区中将这一数据项清除,...
p_Max = &Max;//把函数Max赋给指针变量p, 使p指向Max函数printf("please enter a and b:");scanf("%d%d", &a, &b); c = p_Max(a, b);//通过函数指针调用Max函数printf("a = %d\nb = %d\nmax = %d\n", a, b, c);return0; }intMax(intx,inty)//定义Max函数{intz=-0x7FFFFFFF;...

We can add a getchar() after scanf() to read an extra newline. fgets() and gets() in C language For reading a string value with spaces, we can use either gets() or fgets() in C programming language. Here, we will see what is the difference between gets() and fgets(). fgets(...
int cscanf(char *format[,argument, ...]); 程序例: #include <conio.h> int main(void) { char string[80]; /* clear the screen */ clrscr(); /* Prompt the user for input */ cprintf("Enter a string with no spaces:"); /* read the input */ cscanf("%s", string); ...
rvrs_of_string Generally scanf() ignores the spaces,backslash n,tabs etc while taking input from the user, but by using scanset specifiers we are able to deal with this problem. scanset specifiers are represented by %[]. whether we want to right a character or a string, both can be do...
用法: int cscanf(char *format[,argument, ...]); 程序例: #include <conio.h> int main(void) { char string[80]; /* clear the screen */ clrscr(); /* Prompt the user for input */ cprintf("Enter a string with no spaces:"); ...
另请注意，如果使用者输入的多项式长度超过99个字节，scanf("%[^\n]%*c", userInput)会有未定义的...
