My code,just traverse from the last and if you find a space print the characters before it,now change the end to space-1;This will print till the second word,finally just print the first word using a single for loop.Comment for alter approach.

Program:

#include
int main()
{
 char str[200];
int i,j,k;
scanf("%[^\n]s",&str);
for(i=0;str[i]!='\0';i++);
i=i-1;
for(j=i;j>=0;j--)
{
    if((str[j])==' ')
    {
        for(k=j+1;k<=i;k++)
        {
            printf("%c",str[k]);
        }
        i=j-1;
        printf(" ");
    }

}
for(k=0;k<=i;k++)
{
    printf("%c",str[k]);
}
}
