Algorithm design ideas

1. Use fget Method to get the input string
2. Judge whether there is carriage return in the string , If there is a carriage return, directly set the character to the end of the positioning pointer , Output to prevent carriage return
3. Determine the space in the string , If the space is not empty , Then start printing the characters after the space , And set the current pointer to the tail pointer
4. Be careful strrchr The function returns the last character
5. Print the remaining characters , That is, the content of the first character

Code

#include <stdio.h>
#include <string.h>

int main(){
    
	char s[100];
	char *p;
	fgets(s, 100, stdin); 
	if((p=strrchr(s, '\n')) != NULL){
    
		*p = '\0';
	}
	while((p=strrchr(s, ' ')) != NULL){
    
		printf("%s ", p+1);
		*p = '\0';
	}
	printf("%s", s);
	return 0;
}
