gets(str);
strcat(str," ");
printf("Enter word for search: ");
gets(findw);
printf("Enter a word for replace: ");
gets(replacew);
j=0;
for(i=0;str[i]!='\0';i++)
{
if(str[i]==' ')
{
word[j]='\0';
if(strcmp(word,findw)==0)
{
strcat(strres,replacew);
}
else
{
strcat(strres,word);
}
strcat(strres," ");
j=0;
}
else
{
word[j++]=str[i];
}
