Hello @nirupama1,

  1. You need not convert the character to an integer.
    You can directly apply the same logic to characters also as each element of your char array is a separate digit.

  2. Your code has a logical mistake, which is producing the wrong output:
    c[i]=‘9’-c[i];
    Suppose when c[i]=‘5’,
    ‘9’-c[i] = ‘9’-‘5’ = 57-53(ASCII values) = 4 = EOT(corresponding character in ASCII series)
    Hence, producing a wrong output.

Solution:
c[i]=‘9’-c[i]+‘0’;
For same example,
‘9’-c[i]+‘0’ = ‘9’-‘5’+‘0’ = 57-53+48(ASCII values) = 52 = ‘4’(corresponding character in ASCII series)
Hence, desired output.

Modified Code:

Hope, this would help.
Give a like if you are satisfied.
