Answer:
The program in Python is as follows:
print("Enter a character followed by a phrase",end='')
word = input(": ")
char = word[0]
print("Occurrence: "+str((word.count(char))-1))
Explanation:
The prints an instruction to the user on how to input to the system
print("Enter a character followed by a phrase",end='')
This prompts and gets the user for input
word = input(": ")
This extracts the character from the input string
char = word[0]
This counts and prints the number of occurrence of the extracted character
print("Occurrence: "+str((word.count(char))-1))
