Help with switch

[RandolpNolen]

hey I have problem printing the answer…I have been ask to enter a number and square it or cubing it or finding the square root using a switch function! first it ask you to enter a choice(A-square B-square root C-cube)

<br /> <br /> #include <stdio.h><br /> #include <math.h><br /> <br /> int main(void)<br /> {<br /> int choice;<br /> int number;<br /> char a;<br /> char b;<br /> char c;<br /> <br /> <br /> printf("please enter a choice nn");<br /> printf("A-print the square of the number n");<br /> printf("B- print the square root of the numbern");<br /> printf("C- print the cube of the number. nn");<br /> <br /> <br /> while((choice = getchar () ) !=EOF){ /*loop until user types the End of File */<br /> <br /> switch(choice){<br /> <br /> case 'A':<br /> case 'a':<br /> printf("nEnter a number: n");<br /> scanf("%d", &#038;number);<br /> number = number * number;<br /> printf("Your answer is: n", &#038;number);<br /> break;<br /> <br /> case 'B':<br /> case 'b':<br /> printf("nEnter a number: n");<br /> scanf("%d", &#038;number);<br /> sqrt(number);<br /> printf("Your answer is: n", &#038;number);<br /> <br /> break;<br /> <br /> case 'C':<br /> case 'c':<br /> printf("nEnter a number: n");<br /> scanf("%d", &#038;number);<br /> number=number*number*number;<br /> <br /> printf("Your answer is: n", &#038;number);<br /> <br /> break;<br /> <br /> default:<br /> printf("n <hr class="bbcode_rule" /> ");<br /> printf("nIncorrect choice entered. ");<br /> printf("n <hr class="bbcode_rule" /> nn");<br /> printf("enter a choice: ");<br /> break;<br /> }/*end switch function*/<br /> }/*end while function*/<br /> <br /> return 0;<br /> <br /> }<br /> <br />

my problem is that when you enter any choice it work but when it asks you to enter a number and when you enter the number it prints “incorrect choiced entered”. Whats the problem?

This seems to work:

<br /> <br /> #include <br /> #include <br /> <br /> int main(void)<br /> {<br /> int choice;<br /> int number;<br /> float floatingPointNumber;<br /> char a;<br /> char b;<br /> char c;<br /> <br /> <br /> printf ( "please enter a choice nn" );<br /> printf ( "A-print the square of the number n" );<br /> printf ( "B- print the square root of the numbern" );<br /> printf ( "C- print the cube of the number. n" );<br /> printf ( "Q- Quit n" );<br /> choice = getchar ();<br /> getchar (); //get newline char<br /> <br /> while ( choice != 'Q' &amp;&amp; choice != 'q' )<br /> { /*loop until user types the End of File */<br /> <br /> switch ( choice )<br /> {<br /> <br /> case 'A':<br /> case 'a':<br /> printf ( "nEnter a number: n" );<br /> scanf ( "%d", &amp; number );<br /> getchar (); //get newline char<br /> number = number * number;<br /> printf ( "Your answer is: %i n", number );<br /> break;<br /> <br /> case 'B':<br /> case 'b':<br /> printf ( "nEnter a number: n" );<br /> scanf( "%f", &amp; floatingPointNumber );<br /> getchar (); //get newline char<br /> floatingPointNumber = sqrt ( floatingPointNumber );<br /> printf ( "Your answer is: %f n" , floatingPointNumber );<br /> break;<br /> <br /> case 'C':<br /> case 'c':<br /> printf ( "nEnter a number: n" );<br /> scanf ( "%d", &amp; number );<br /> getchar (); //get newline char<br /> number = number * number * number;<br /> printf ( "Your answer is: %i n", number );<br /> break;<br /> case 'Q':<br /> case 'q':<br /> printf ( "goodbye .... n " );<br /> break;<br /> <br /> default:<br /> printf ( "n <hr class="bbcode_rule" /> " );<br /> printf ( "nIncorrect choice entered.
