Program in C
Here is the source code of the C Program to Reverse words in a given string.
Code:
#include<stdio.h>
#include<string.h>
main()
{
int in=0,out=0,p=0;
char str[100]={0},sub_str[100][100]={0};
printf("Enter your String:");
gets(str);
//splitting Input String into sub string
while(str[p]!='\0')
{
out=0;
while(str[p]!=' ' && str[p]!='\0')
{
sub_str[in][out]=str[p];
p++;
out++;
}
sub_str[in][out]='\0';
in++;
if(str[p]!='\0')
{
p++;
}
}
printf("After reversing words in a given string is:");
//Here 'in' variable count number of word present in the given string
for(out=in-1;out>=0;out--){
printf("%s ",sub_str[out]);
}
}
Enter your String:C STRING PROGRAM
After reversing words in a given string is:PROGRAM STRING C
Program in C++

getline(cin,str);
int in=0,out=0,p=0;
int len=0;
char sub_str[100][100]={0};
for(in=0;str[in]!='\0';in++)
{
len++;
}
//splitting Input String into sub string
while(str[p]!='\0')
{
out=0;
while(str[p]!=' ' && str[p]!='\0')
{
sub_str[in][out]=str[p];
p++;
out++;
}
sub_str[in][out]='\0';
in++;
if(str[p]!='\0')
{
p++;
}
}
cout<<"After reversing words in a given string is :";
//Here 'in' variable count number of word present in the given string
for(out=in-1;out>=0;out--){
cout<<sub_str[out]<<" ";
}
}
Enter your String:c++ string question
After reversing words in a given string is :question string c++
Program in Java

public class ReversingWords {
public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
String str;
System.out.println("Enter your String:");
str=cs.nextLine();
//splitting Input String into sub string
String[] sub_str=str.split("\\s");
int out;
System.out.print("After reversing words in a given string is:");
//Here 'in' variable count number of word present in the given string
for(out=sub_str.length-1;out>=0;out--){
System.out.print(sub_str[out]+" ");
}
cs.close();
}
}
Enter your String:
