title: How to covert the first letter of a string to a uppercase
body: <p>This is for a school assignment. The goal of this function is to randomly select a word from each array and create a new array with the first letter of each sentence capitalized, spaces between each word, and a period in the end 20 times. The sentence follows the format article, noun, verb, preposition, article, and noun. </p>
  
  <p>My question is how do I go about capitalizing the first letter of each sentence? I tried to set the first position in the string to equal the char at that position - 32, but that just crashes the program. </p>
  
  <pre><code>void randomize(void) {
  
      char *article[] = {"the", "a", "one", "some", "any"};
      char *noun[] = {"boy", "girl", "dog", "town", "car"};
      char *verb[] = {"drove", "jumped", "ran", "walked", "skipped"};
      char *preposition[] = {"to", "from", "over", "under", "on"};
      char *sentence[6];
  
      int running = 1;
  
      while(running){
  
          int location = rand()%5;
  
          char *captFirstLetter = article[location];
  
          captFirstLetter[0] = captFirstLetter[0] - 32 ;
  
          sentence[0] = captFirstLetter;
  
          sentence[1] = noun[rand()%5];
  
          sentence[2] = verb[rand()%5];
  
          sentence[3] = preposition[rand()%5];
  
          sentence[4] = article[rand()%5];
  
          sentence[5] = noun[rand()%5];
  
          for(int i = 0; i &lt; 7; i++){
              printf("%s%s%s", (i == 6) ? "" : sentence[i], (i &gt; 4) ? "" : " ", (i == 5)? ".\n" : "" );
          }
          running ++;
  
          if(running == 21){
              running = 0;
          }
      }
