Question

Write a program that uses the random number generator to create sentences. The program should use four arrays of pointers to char called article, noun, verb and preposition. The sentences are constructed in the following order: article, noun, verb, preposition, article, noun. The program should generate 20 sentences. Capitalize the first letter. The arrays should contain:

article "the", "one", "a", "some", "any"

noun "boy", "girl", "dog", "town", "car"

verb "drove", "jumped", "walked", "ran", "skipped"

preposition "to", "from", "over", "under", "on"

Here is the code I have so far:

void sentenceGenerator(const char *const art[], const char *const noun[],
   const char *const verb[], const char *const prep[])
{
   int i;
   for (i = 0; i < 20; i++)
   {
       printf("%s %s %s %s %s %s\n",
           art[rand() % SIZE],
           noun[rand() % SIZE],
           verb[rand() % SIZE],
           prep[rand() % SIZE],
           art[rand() % SIZE],
           noun[rand() % SIZE]);
   }
}

int main()
{
   const char *art[SIZE] = { "the", "a", "one", "some", "any", };
   const char *noun[SIZE] = { "boy", "girl", "dog", "town", "car", };
   const char *verb[SIZE] = { "drove","jumped", "ran", "walked", "skipped", };
   const char *prep[SIZE] = { "to", "from", "over", "under", "on", };
   srand(time(0));
   sentenceGenerator(art, noun, verb, prep);
   system("pause");
   return 0;
}

How can I get the sentences to capitalize the first letter and put a period at the end?

Modified code is written in bold underline.

#include<stdio.h>
#include<conio.h>
#include <stdlib.h>
#include<time.h>
#include<ctype.h>
#define SIZE 5

void sentenceGenerator( char * art[], char * noun[],
char * verb[], char * prep[])
{
int i;
   char* first;
   char ch;
for (i = 0; i < 20; i++)
{
  
          
          first=art[rand() % SIZE];
ch=*first; //store first letter in ch
  printf("%c",toupper(ch)); //make ch capital and print
printf("%s ",(first+1)); //print remaining letters in art

       printf(" %s %s %s %s %s\n",
noun[rand() % SIZE],
verb[rand() % SIZE],
prep[rand() % SIZE],
art[rand() % SIZE],
noun[rand() % SIZE]);
}
}
int main()
{
char *art[SIZE] = { "the", "a", "one", "some", "any" };
char *noun[SIZE] = { "boy", "girl", "dog", "town", "car" };
char *verb[SIZE] = { "drove","jumped", "ran", "walked", "skipped" };
char *prep[SIZE] = { "to", "from", "over", "under", "on" };
srand(time(0));
sentenceGenerator(art, noun, verb, prep);
system("pause");
return 0;
}
