About gets function of usage:
Prototype: function only one parameter, the parameter of type char * type, str can be a pointer type variable name, or the name of a character array;
# include <stdio.h>
char* gets(char* str);gets () function is the function to read a string of characters stored in the memory space pointed to by a pointer variable str from the input buffer.
Some differences with scanf function gets the ------- will empty the buffer?
When using the gets function, usually in the final knock the Enter key to end this function gets, if it gets back again to enter a character, you can directly input function gets the Enter key has been cleared (empty the buffer), but If it gets to the middle again necessary to add a getchar with scanf () function to store the return key knock
# include <stdio.h>
int main()
{
int n;
char x,a[10];
scanf("%d",&n);
x=getchar(); /*用getchar清空缓冲区*/
gets(a);
return 0;
}
