C Program to reverse words in a line
Implementation
Now, we shall see the actual implementation of the program −
#include <stdio.h> #include <string.h> int string_length(char s[]) { int i = 0; while(s[i]!='\0') i++; return i; } void string_reverse(char st[]) { int i,j,len; char ch; j = len = string_length(st) - 1; i = 0; while(i < j) { ch = st[j]; st[j] = st[i]; st[i] = ch; i++; j--; } } int main (void) { char line[] = "Taj Mahal is one of the seven wonders of the world"; char reverse[100]="",temp[50]; int i,j,n; n = string_length(line); for(i = 0; i < n; i++) { for(j = 0; i < n && line[i]!=' '; ++i,++j) { temp[j] = line[i]; } temp[j] = '\0'; string_reverse(temp); strcat(reverse, temp); strcat(reverse, " "); } printf("Original - %s\n", line); printf("Reversed - %s\n",reverse); return 0; }
Output
Output of this program should be −
Original - Taj Mahal is one of the seven wonders of the world Reversed - jaT lahaM si eno fo eht neves srednow fo eht dlrow
