I have a problem with this code which is supposed to make a reverse sentence.
Example:
Input
Hi my name is Robert
Output
Robert is name my Hi
#include <stdio.h>
#define LEN 50
int main(void)
{
char input, terminator = 0, sentence[LEN+1] = {0};
int i, j, last_space = LEN + 1, posc=0;;
int pos[]={0};
printf("
Enter a sentence: ");
for (i = 0; (input = getchar()) != '
'; i++)
{
if(input== ' '){
pos[posc]=i;
posc++;
}
if (input == '.' || input == '?' || input == '!')
{
last_space = i;
terminator = input;
break;
}
sentence[i] = input;
}
if (terminator == 0)
{
printf("Sentence needs a terminating character. (./?/!)
");
return 0;
}
printf("Reversal of sentence: ");
for (i = last_space; i > 0; i--)
{
if (sentence[i] == ' ')
{
for (j = i + 1; j != last_space; j++)
{
putchar(sentence[j]);
}
last_space = i;
putchar(sentence[i]);
}
}
while (sentence[i] != '' && sentence[i] != ' ')
{
putchar(sentence[i++]);
}
printf("%c
", terminator);
for(int i=sizeof(pos)-1; i>0; i--){
printf("%.*s", sentence[pos[i-1]], sentence[pos[i]]);
}
printf("%c
", terminator);
return 1;
}
This keeps crashing because of the method at the bottom here:
printf("%c
", terminator);
for(int i=sizeof(pos)-1; i>0; i--){
printf("%.*s", sentence[pos[i-1]], sentence[pos[i]]);
}
printf("%c
", terminator);
return 1;
}
Can someone help me fix this snippet of code for me so that both methods work when run? Thanks.
