scanf("%lf", &(a.x));
scanf("%lf", &(b.y));

replace the scanf with this that is remove the newline.

In the warning message it correctly refers to printf.so, I was not sure which is correct?Leave a comment:

Two reasons i can think of
1. In your actual source code you have not included
2. The installation is not proper and the compiler is not able to find the stdio.h file or may be it is pointing to different stdio.h fileCode:#include <stdio.h>

For a multi-line define use the line-continuation character, \.
Your code will then look something like this
Code:#define md1(i, m, n)\ { \ factor= 1+i/m;\ ratio=(12/m)*(pow(factor,m*n)-1)/(i/m); \ )Leave a comment:

I plan to modify the code to avoid using MAX. Can I use something like this
...Code:#include <stdio.h> void Test1(void); void Test2(void); void (*funp[])(void)= { Test1, Test2, }; int main(void) { int index=0; int size = sizeof(funp)/sizeof(funp[0]); for(index=0;index < size; index++) { (*funp[index])();Leave a comment:

i thought this an array of function pointers.
I get proper output if I use MAX equal to 2. I am getting confused.Code:void (*funp[])(void)= { Test1, Test2, };
Or should i have said it is an array of pointers to function.Leave a comment:

This is the program i am trying to execute
...Code:#include <stdio.h> #define MAX 3 void Test1(void); void Test2(void); void (*funp[])(void)= { Test1, Test2, }; int main(void) { int index=0; for(index=0;index <MAX; index++) { (*funp[index])(); } return 0; }Leave a comment:

Array of function pointers
Small doubt regarding function pointers as you can see the array of function pointers is initialized with two elements, but i am calling up to 3. In such cases what is the behavior of the program? How to avoid using MAX?
...Code:void Test1(void); void Test2(void); #define MAX 3 for(i = 0; i < MAX; i++) { (*funcptr[i])(); } void (*funcptr[])(void) = { Test1, -
It was excellent article i had lot of confusion in multidimensiona l arrays, it all got cleared. But it would have been great if explained that after passing the multidimensiona l array as argument to a function how do you access the elements of the array inside the function.Leave a comment:

I made the following attempt, but if fails
...Code:#include<stdio.h> #include<limits.h> int main(void) { int number=0; unsigned short factorial=1; printf("Enter the number to calculate factorial\n"); scanf("%d",&number); printf("us= %d\n",sizeof(unsigned short)); while(number>1) { factorialLeave a comment:

Finding maximum value of a data type
I was trying the program to calculate the factorial of a number. The program is to identify the value of number at the which the factorial crosses the range of the data type. How should i do this? Please help me for the logic. I want to accommodate all kinds of data types.
Thanks. -
Question is not very clear.Leave a comment:

The option I can think of is a ternary operator.Leave a comment:

I think you have to choose different memory model from the project settings.Leave a comment:

You can declare an array of int of enough size like
And use scanf something likeCode:int array[100];
You can loop from k 0 to num-1 instead of 1 to num.Code:for(k=0; k < num; k++) scanf("%d",&array[k])Leave a comment:

It works for me. What exactly is the problem you are facing. Better initialize all the local variables i, num1, num2 to 0.Leave a comment:

is used for printing strings. It will try to print till a null character is found. In case ofCode:int fprintf ( FILE * stream, const char * format, ... );
Writes an array of count elements, each one with a size of size bytes, from the block of memory pointed by ptr to the current position in the stream and does not look...Code:size_t fwrite ( const void * ptr, size_t size, size_t count, FILE * stream );

To read from a file there should be fscanf. That is missing in your program.Leave a comment:

Great I was not aware of the background of \0 and the way to use it. Thank you.Leave a comment:

Just one doubt I have, you said to avoid writing \0, but in the case of scanf the function by default adds \0. So, how to handle this case.Leave a comment:
