Capitalize first letter in word

Here given code implementation process.

//C Program 
//Capitalize first letter in word
#include <stdio.h>

void capitalize(char str[],int size)
{
  for (int i = 0; i <= size; ++i)
  {
    
    if((i==0 && str[i]>='a' && str[i] <='z')||
      (  i>0 && str[i-1]==' ' && str[i]>='a' && str[i] <='z'))
    {
      str[i] = str[i] - 32;
    }
  }
}
int main()
{

  char str[]="I have an logic to solve this problem";
  //Get the size
  int s=sizeof(str)/sizeof(str[0]);
  
  printf("%s\n",str );
  
  capitalize(str,s-2);
  
  printf("%s\n",str );
  

  return 0;
}

Output
