I've just encountered a weird problem, I'm trying to printf an integer variable, but I forgot to specify the variable name, i.e.
printf("%d");
instead of
printf("%d", integerName);
Surprisingly the program compiles, there is output and ... |
I wrote this tiny code:
#include <stdio.h>
int main() {
size_t temp;
temp = 100;
printf("lld=%lld, ld=%ld, u=%u\n", temp, temp, temp);

I need to print a variable which is a COLORREF.

What should the code print? 0 or any garbage value or will it depend on the compiler?
#include <stdio.h>
int a;
int main()
{
printf("%d\n",a);
return 0;
}

I just stumbled upon the idea that since printf returns the no.of characters it has printed to the output stream why not use it to find length of any variable in ... |

Since you are using string you must be using C++. Since you are using C++ you should be using cout not printf. If you were using cout you could use the setw io manipulator to set the width. As an aside there is a method to pass printf a varible whose contents is used as field width. A quick google should ... |
Hi friends!! As we know that the input parameters in a function is fixed when the function is defined but how does printf processes variable number of input arguments ? For example: 1. printf("Hey! how are you"); /*No. of arguments = 1*/ 2. printf("Sum of %d and %d is %d",a,b,c"); /* No. of arguments = 4*/ I know it uses three ... |
Below is code with description and questions. Any help would be greatly appreciated. Yes, I am new to C programming. Code: #include #include int DtTm; int DtTm2; int getDateTime(void); int main(void) { /* If the following printf is not executed * then group #1 will not display any dates * BUT group #2 does display dates. * If the ... |

I have a situation where I want to set a field width to be the size of the greatest input (length of char*). I know in c++ you can use setw manipulators and there is the %20s (or other number) for printf, but what if you dont know the width of the output until after the read, can you use a ... |
char *target = "pass" is a provision by the compiler to do something you can only do at compile time: generate a C string and declare a pointer to it in one swell foop. The pointer is a local, the string itself is in memory the compiler lends you and declares to be unmodifiable (const). You can't write to it with ... |
Hi, I've got an odd error. I'm writing an simple emulator for a kernel and trying to implement a cache. The if statement in the code below functions irratically. The function 'cache_read' is passed an address. This is masked and compared to a stored address. This code should fail as the stored address is 0 and the passed address in non-zero. ... |
