Declare a character variable letterstart. write a statement to read a letter from the user into letterstart, followed by statements that output that letter and the next letter in the alphabet. end with a newline. hint: a letter is stored as its ascii number, so adding 1 yields the next letter. sample output assuming the user enters 'd': de 1 2 3 4 5 6 7 8 9 10 11 12 13 #include int main(void) { char startword=' '; int startint=0; printf("\n"); scanf("%c",& start word); starting=(int) startword; printf("%c%c",startword, startint+1); return 0; }
