Answer 1

//C program to split a string

#include <stdio.h>
#include <string.h>
int main()
{
char s[100], word[100];
int i=0,j=0;
scanf(" %[^\n]", s);
while(s[j]!='\0'){
//strcpy(word[i], s[j]); //strcpy takes char pointer not chars

word[i]=s[j];
if(s[j]==' ' || s[j+1]=='\0'){
word[i+1]='\0'; //MARK THE END OF WORD SO OTHER CHARACTERS WON'T SHOW UP
printf("%s\n", word);
i=-1; //i++ below makes it zero
}
i++;
j++;
}
return 0;
}

You also need to think about how to handle a sentence with multiple spaces. If your goal is to split it into words at space boundaries you could use strtok() in string.h to simplify it:

char s[100], *word;

fgets(s, sizeof(s), stdin);
for (word = strtok(s, " \n"); word; word = strtok(NULL, " \n"))
puts(word);
