C Program to Print Reverse Words in a Line String

In this c programming example we will learn how to print reverese words in line string

Algorithm

Take an array of char which we need to print the string words
Calculate length of the char array
take temp array with specified length
Now loop the char array and take individual character and store into temp array
Print the reverse char array

#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[] = "C Programming Examples for beginners";

int i,j,n;

n = string_length(line);

char reverse[n],temp[n];

reverse[n]="";

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("Input String - %s\n", line);

printf("Reversed Words String - %s\n",reverse);

return 0;
}
