//additionally include string.h for getting the length of a string with strlen(), and include cytype.h to convert a character to uppercase with toupper()

int main(void){
    string name = get_string();//get the name
    char charPrevious = ' ';//keep track of previous character

    for(int i = 0; i < strlen(name);i++){//look at each character in the string
        if(charPrevious == ' '){
           printf("%c", toupper(name[i]));//if the previous  character was a space, print the initial
        }
        charPrevious = name[i];//set the previous initial to equal the current one
    }
    printf("\n");//print \n because cs50
