This challenge will help you to learn how to take a character, a string and a sentence as input in C.
To take a single character as input, you can use scanf("%c", &ch ); and printf("%c", ch) writes a character specified by the argument char to stdoutchar ch;
scanf("%c", &ch);
printf("%c", ch);
This piece of code prints the character .
You can take a string as input in C using scanf(“%s”, s). But, it accepts string only until it finds the first space.
In order to take a line as input, you can use scanf("%[^\n]%*c", s); where is defined as char s[MAX_LEN] where is the maximum size of . Here, [] is the scanset character. ^\n stands for taking input until a newline isn't encountered. Then, with this %c, it reads the newline character and here, the used indicates that this newline character is discarded.
Note: The statement: scanf("%[^\n]%*c", s); will not work because the last statement will read a newline character, \n, from the previous line. This can be handled in a variety of ways. One way is to use scanf("\n"); before the last statement.
