Hello, in my program, i ask them to enter data, then i ask if they want to do it again (Y) - which repeats it again; or not (N) in which case it exits the program.
My problem is: It works fine the first time, but when i type Y, it repeats ''Enter Text:'' and also prints ''Again? (Y/N):'', so that i can't answer the first part.
Anyone know why it's doing this? It is having the same error as if i was using scanf and needed to 'flush' it (yes i know fflush(stdin) doesn't work :D)
Here's the code:
Code:#include <stdio.h>
void fConvert(char[]);
int main(void)
{
char cText[100], cInputYN[5], cAnsYN;
int xAgain, iInputError;
do
{
printf("Enter text:");
fgets(cText, 100, stdin);
fConvert(cText);
do
{
printf("\n\nAgain? [Y/N]");
fgets(cInputYN, 2, stdin);
cAnsYN = cInputYN[0];
if (cInputYN[0] != '\n')
{
if (cAnsYN == 'Y' || cAnsYN == 'y')
{
xAgain = 1;
iInputError = 0;
}
else if (cAnsYN == 'N' || cAnsYN == 'n')
{
xAgain = 0;
iInputError = 0;
}
else
{
printf("\n\tInvalid letter. Please try again.\n");
iInputError = 1;
}
}
else
{
printf("\n\tInvalid Input. Please try again.\n");
iInputError = 1;
}
}while (iInputError == 1);
}while (xAgain == 1);
printf("\n\tThanks for using B-Cipher V0.1.\n\n");
return 0;
}
void fConvert(char b[100])
{
int a = 0;
for(a; b[a]!='\0'; a++)
{
switch(b[a])
{
case 'a':
printf("t");
break;
case 'b':
printf("e");
break;
case 'c':
printf("s");
break;
case 'd':
printf("l");
break;
case 'e':
printf("a");
break;
case 'f':
printf("b");
break;
case 'g':
printf("c");
break;
case 'h':
printf("d");
break;
case 'i':
printf("f");
break;
case 'j':
printf("g");
break;
case 'k':
printf("h");
break;
case 'l':
printf("i");
break;
case 'm':
printf("j");
break;
case 'n':
printf("k");
break;
case 'o':
printf("m");
break;
case 'p':
printf("n");
break;
case 'q':
printf("o");
break;
case 'r':
printf("p");
break;
case 's':
printf("q");
break;
case 't':
printf("r");
break;
case 'u':
printf("u");
break;
case 'v':
printf("v");
break;
case 'w':
printf("w");
break;
case 'x':
printf("x");
break;
case 'y':
printf("y");
break;
case 'z':
printf("z");
break;
case ' ':
printf(" ");
break;
case '\n':
break;
default:
printf("\nError, was not a letter\n");
}
}
}
