using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.




#include #include struct stu { int i; char j; }; union uni { int i; char j; }; void main() { int j,k; clrscr(); struct stu s; j=sizeof(s); printf("%d",j); union uni u; k=sizeof(u); printf("%d",k); getch(); } what is value of j and k.

write an algorithm to display a square matrix.


The purpose of this exercise is to benchmark file writing and reading speed. This exercise is divided into two parts. a). Write a file character by character such that the total file size becomes approximately >10K. After writing close the file handler, open a new stream and read the file character by character. Record both times. Execute this exercise at least 4 times b). Create a buffer capable of storing 100 characters. Now after generating the characters, first store them in the buffer. Once the buffer is filled up, store all the elements in the file. Repeat the process until the total file size becomes approximately >10K.While reading read a while line, store it in buffer and once buffer gets filled up, display the whole buffer. Repeat the exercise at least 4 times with different size of buffer (50, 100, 150 …). Records the times. c). Do an analysis of the differences in times and submit it in class.
