clear echo "Enter a number" read n sd=0 rev=0 while [ $n -gt 0 ] do sd=$(( $n % 10 )) rev=$(( $rev *\ 10 + $sd )) n=$(( $n / 10 )) done echo "Reverse number of entered digit is $rev"
From the above code I am unable to get the required output. Instead, this error is displayed.
./Display: line 17: 0 *\ 10 + 4 : syntax error: operand expected (error token is "\ 10 + 4 ") Reverse number of entered digit is 0
I don't know why this error is displayed, please help me to figure it out.
