Promgram Code:
#Function to convert a hex character to its decimal integer value.
def hexToDecimal(hexChar):
decimal = 0
if hexChar.isdigit():
# Convert the hex digit to decimal if it is a digit
decimal = int(hexChar)
else:
# Convert the hex character to uppercase
hexChar = hexChar.upper()
if hexChar == 'A':
decimal = 10
elif hexChar == 'B':
decimal = 11
elif hexChar == 'C':
decimal = 12
elif hexChar == 'D':
decimal = 13
elif hexChar == 'E':
decimal = 14
elif hexChar == 'F':
decimal = 15
return decimal
# Prompt the user to enter a hex character
hexChar = input("Enter a hex character: ")
# Convert the hex character to decimal
decimal_value = hexToDecimal(hexChar)
# Display the result
print("The decimal value is", decimal_value)
