When i am entering single character instead of 'miz' then it is working great. But when i am using multi character like 'miz' it is showing error output. i did this program with c++ it is working but not working in c.When i am running this program it is showing {warning] multi character constant.
Code:
#include<stdio.h> #include<string.h> main() { char a; printf("Please Enter your First Name: "); scanf("%s",&a);
Fresh storage string not released before return A memory leak has been detected. Storage allocated locally is not released before the last reference to it is lost. (Use -mustfreefresh to inhibit warning) string_read.c:6:7: Fresh storage string created
Here is my code. I am combining two words and sorting the merge word in alphbetical order. The compiler giving me warning error
Program:12:4: warning: format '%s' expects argument of type 'char *', but argument 2 has type 'char (*)[100]' [-Wformat] Program:14:4: warning: format '%s' expects argument of type 'char *', but argument 2 has type 'char (*)[100]' [-Wformat]
I'm doing some file input/output work here in C and received this warning during compilation (GCC). My research indicates that this error is in response to white space or a character cancellation function or something like that. I'm not 100% sure exactly what it means. My code works fine, but the following warning does appear.
Code: warning: unknown escape sequence: '40'
Here's my code (excluding a bunch of comments at the bottom of the file).
I believe the error I received has to do with either the ' ' I used when appending text to my file, or something to do with there being a space in the file name itself.
I'm working on my program that takes input of the employees' first and last name, their payrate, their deferred from check and also the amount of hours they have worked which then the gross is calculated and also the taxes are calculated by an external function. In the program design it is necessary to put arrays which I have done, but when i compile I receive warning messages
Code: warning: format '%s' expects argument of type 'char*', but argument 3 has type 'double'
Warning: format '%f' expects a matching 'double' argument [-Wformat] which I believe is causing my program to just give me garbage when I run it. What do those warnings mean?
Double values are stored in text file. 23.5 36.8 34.2 ... My teacher told me to read them character by character and then make words, like i have to read "2" "3" "." "5" and now have to make it or treat it as word and then using atoi(). I have to convert it into double. but i dont know how to do this....
I am trying to write a Fraction class and getting the following warning when compiling my code :
Fraction.cpp: In constructor 'Fraction::Fraction(double)': Fraction.cpp:8: warning :converting to 'int' from 'double'
My Fraction.cpp class looks like :
#include "Fraction.h" Fraction::Fraction(int n, int d):num(n),den(d) { cout << This is double param constructor <<endl; } Fraction::Fraction(double d):num(d),den(0)
I am trying to create a multiple choice quiz so I can learn the menu at my new job, while doing a side project but I am having a warning when outputting. Speaking of side projects, is this a kind of side project people are looking for on a resume?
I know that if I just use "return" by itself the warning goes away but fails to exit when the error occurs. I also believe this may not be the correct use of stderr. But I need the program to exit when an error has occurred.
Now I was just curious if there is easier way to implement this condition. To use less code. When I extend the condition to hour:minute:second the code would only grow fast. Also I know I should not use "magic numbers" but it is only for the demonstration.
I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.
#include <iostream> class Hello { public: void Test() {

As i know a non-constant member function cant be called inside a constant member function but how the above code has been compiled successfully and giving the expected result .
