getch() function used to freeze the output screen after
the result and when the any key entered and return an ASCII
value of that character. But don't show what character was
entered by the user.
whereas getche() function shows ASCII value as well as
entered charachter.

Answer / piyush srivastava
getch() function works to get character from the user,but it
is used to hold the output,it may have the alternatives but
it the easiest way to perform this action.
getch() only read the character from the user but getche
also display it on the output screen .

Answer / yashwant/9015785079
When you will run program, the program will exit only when you press a character, note that we are talking about a character.
so try pressing numlock, shift key etc (program will not exit if you press these keys) as these are not characters. Also try the program by removing getch(),in this case program will exit without waiting for a character being pressed from keyboard.
Common use of getch is that you can view the output (if any) of your program without having to open the output window if you are using turbo c compiler or if you are not running your program from command prompt.

Explain this code. #include <stdio.h> void f1(int *k) { *k = *k + 10; } main ( ){ int i; i = 0; printf (" The value of i before call %d \n", i); f1 (&i); printf (" The value of i after call %d \n", i); }
Question 1: You want to conduct a survey within your classroom, on the quality of canteen’s food. You ask each of your class fellows to rank the quality of food between 1 and 5 (1 representing excellent quality and 5 representing worst quality). During the survey, you make a list containing the roll# of student and the opinion given by that student. The list can be as follow Roll # Opinion 234 1 235 1 236 5 237 1 238 2 239 3 240 5 241 5 242 1 To get the results of the survey, you need to determine the frequency of each opinion value. The frequency of an opinion is determined by counting the number of students giving that opinion. For example, for the above list the frequency of opinion value 1 is 4 and frequency of opinion value 4 is 0. After getting the frequency of each opinion, you can easily judge about the quality of the food by seeing through the frequency of each opinion. You need to develop a program to calculate the results of this survey. The program inputs the opinion of 50 students and counts the frequency of each opinion. It then displays a report showing the frequency of each opinion. Sample output: Opinion Frequency Remarks 1 5 Excellent 2 10 Good 3 15 Normal 4 10 Bad 5 10 Really bad
write an interactive C program that will encode or decode a line of text.To encode a line of text,proceed as follows. 1.convert each character,including blank spaces,to its ASCII equivalent. 2.Generate a positive random integer.add this integer to the ASCII equivalent of each character.The same random integer will be used for the entire line of text. 3.Suppose that N1 represents the lowest permissible value in the ASCII code,and N2 represents the highest permissible value.If the number obtained in step 2 above(i.e.,the original ASCII equivalent plus the random integer)exceeds N2,then subtract the largest possible multiple of N2 from this number,and add the remainder to N1.Hence the encoded number will always fall between N1 and N2,and will therefore always represent some ASCII character. 4.Dislay the characters that correspond to the encoded ASCII values. The procedure is reversed when decoding a line of text.Be certain,however,that the same random number is used in decodingas was used in encoding.
