Question

that reads data from standard input one character at a time and output the results to standard output.
1. replace characters '_' '/ ' ':' ' ? ' ' &' and ' ' with its corresponding ascii code

2. Interchange the case of the alphabetical letters.

3. delete non_ascii characters.

Answer 1

Hi,



The following should give you an idea of char to ascii conversions.



unsigned char ch;

ch = getchar();

printf("%c - %d", ch, ch );

Answer 2

replace characters '_' '/ ' ':' ' ? ' ' &' and ' ' with the ascii code



int ch; // int 'cause getchar() returns an int (so it can hold EOF)

ch=getchar();

if(ch>127) printf("not ASCII/n");

if(ch=='_' || ch=='/' || ch== ';' || ch=='?' || ch=='&' || ch=='?')

printf("%d",ch);// print its decimal value

else

printf("%c",ch);// print it as a character glyph
