Given a word of English, asking you to write a program, all the words of the sentence order reversed output.
Input format: test input comprising a test case, given the string length does not exceed a total of 80 in a row. String composed of several words and a number of spaces, where the word is English letters (case is case) consisting of string, separated by a space between words, the input end of the sentence to ensure that no extra space.
Output format: one row for each test case output, output sentence after the reverse.
Sample input:
the Hello World Here Come the I
sample output:
Come the I Here the Hello World
#include <stdio.h>
#include <cstring>
//用二维数组解决
void split(char *str) {
char ans[90][90];
int length = strlen(str);
int r = 0, c = 0;
//Hello World Here I Come
for (int i = 0; i < length; i++) {
if (str[i] != ' ') {
ans[r][c++] = str[i];
} else {
ans[r][c] = '\0';
r++;
c = 0;
}
}
for (int i = r; i >= 0; i--) {
printf("%s", ans[i]);
if (i > 0)
printf(" ");//控制最后一个空格
}
}
int main() {
char str[80];
while (gets(str)) {
split(str);
printf("\n");
}
}
