pointer array using scanf(), but when I run the program, I get segmentation faults and core dumps. The problem occurs when the program calls scanf(). I don't know what is wrong with it. Here is my code: #include "stdio.h" #define SIZE 5 void input(char *string, char *string2)...

this sequence is converted to a sequence of characters in the same manner as thewcstombssubroutine. ThePointerparameter should be a pointer to the initial byte of achar, signedchar, or unsignedchararray large enough to hold the sequence and a terminating null-character code, which is automaticall...
The puts() function writes the string str with a newline character ('\n') at the end to stdout. On success, a non-negative value is returned.Here is the syntax for the gets() function:int puts(const char* str);str is the pointer to an array of chars where the C string is ...
方法: int输出结果为4,char输出结果为1符号:无符号的八位数字表示数值,有符号的八位的第一位数字表示正负(0代表正数,1代表负数) char与signed char同义1.变量在内存中是有位置的2.修改变量即是修改内存,读取变量即是读取内存 注意事项: 当用scanf来接收用户输入的整数时,只能用int型变量,不能用short/char型...
char b[2]; scanf("%s", b); printf("%s\n", b); } 如果输入的字符比较多例如10个,就会seg fault,可见scanf是不安全的,没有检查缓冲区。 同样,把上面的scanf换成gets,效果是一样的。(而且编译的时候有warning,不让用gets)。 fgets是安全的,这样用法: ...
