     You need to declare your functions with the same signature as their definitions. For example:

     int display(int,int,int);-

     Should be:

     int display(int queue[MAX], int front, int rear);-

   • Programming in C, Using pow function

     Top Answer

     Answered Dec 10, 2015 · 3 votes

     Please include a minimum working example with your code.

     Anyway, it works on my system (Debian GNU/Linux testing, gcc 5.2.1):

     #include <math.h>#include <stdio.h>int main() {- float a,b,c; scanf("%f",&a); scanf("%f",&b); scanf("%f",&c); if ((pow(b,2.0)-4*a*c)<0) printf("\nNo roots!\n"); else if((pow(b,2.0)-4*a*c)>0) { printf("\nRoots=%.2f and %.2f\n", (-b+pow(b*b-4*a*c,0.5))/(2*a), (-b-pow(b*b-4*a*c,0.5))/(2*a)); } else printf("\nBoth roots are %.2f\n",-b/(2*a)); return 0;}

     If I enter 1, 14, 49, the program answers Both roots are -7.0. But this may vary among systems, because you are using floating point arithmetic and I don't know how your pow() function was implemented. Not all real numbers can be represented on a computer -- here's a good description of how it works for single precision floats. And each compiler/runtime environment will have a possibly different implementation of the math library (which includes pow, that you have used).

     So, I would avoid pow at all if possible. Use b*b instead, and save pow for when you really need it. And as Tom Karzes mentioned, sqrt is also better than using pow for calculating square roots.

     One last thing: calculating the discriminant only once would make your program more readable:

     #include <math.h>#include <stdio.h>-int main() { float a,b,c; float delta; scanf("%f",&a); scanf("%f",&b); scanf("%f",&c); delta = b*b-4*a*c; if (delta<0) printf("\nNo roots!\n"); else if(delta>0) printf("\nRoots=%.2f and %.2f\n", (-b+sqrt(delta))/(2*a), (-b-sqrt(delta))/(2*a)); else printf("\nBoth roots are %.2f\n",-b/(2*a)); return 0;}

     One more thing you may try is to use double instead of float, so you'll have more precision (not relevant depending on the numbers you'll be using, but it's a good idea to use doubles if you don't have huge matrices of numbers that could take too much memory -- a double takes twice as memory as a float to represent).

   • C Programming - #define function

     Top Answer

     Answered Jun 21, 2017 · 0 votes

     This is what happens in your case:

     int main() { int m,n; m=3+2>3 ? 2:3; //(3+2)>3 ? 2 : 3 = 2 n=2*3>2 ? 3:2; //(2*3)>2 ? 3 : 2 = 3 printf("m=%d, n=%d\n",m,n); return 0;}

     If you rewrite your defined to #define MAX(a,b) ((a)>(b) ? (a):(b))

     then you will have desired output as it will be evaluated to:

     //Correct way with parenthesisint main() { int m,n; m=3+((2)>(3) ? (2):(3)); //6 n=2*((3)>(2) ? (3):(2)); //6 printf("m=%d, n=%d\n",m,n); return 0;}

   • Function of (char)getchar() in C programming

     Top Answer

     Answered Jun 24, 2022 · 5 votes

     (char)getchar() is a mistake. Never use it.

     getchar returns an int that is either an unsigned char value of a character that was read or is the value of EOF, which is negative. If you convert it to char, you lose the distinction between EOF and some character that maps to the same char value.

     The result of getchar should always be assigned to an int object, not a char object, so that these values are preserved, and the result should be tested to see if it is EOF before the program assumes a character has been read. Since the program uses c to store the result of getchar, c should be declared as int c, not char c.

     It is possible a compiler issued a warning for c = getchar(); because that assignment implicitly converts an int to a char, which can lose information as mentioned above. (This warning is not always issued by a compiler; it may depend on warning switches used.) The correct solution for that warning is to change c to an int, not to insert a cast to char.

     About the conversion: The C standard allows char to be either signed or unsigned. If it is unsigned, then (char) getchar() will convert an EOF returned by getchar() to some non-negative value, which will be the same value as one of the character values. If it is signed, then (char) getchar() will convert some of the unsigned char character values to char in an implementation-defined way, and some of those conversions may produce the same value as EOF.

    What is a disjoint set?

    • In other words, a disjoint set is a group of sets where no item can be in more than one set. It is also called a union–find data structure as it supports union and find operation on subsets. Let’s begin by defining them: Find: It determines in which subset a particular element is in and returns the representative of that particular set.

    What is disjoint union?

    • The disjoint union of sets is different from the regular union operation of sets. The disjoint union is a binary operation on two disjoint sets. After performing the disjoint union operation, the resultant set should satisfy the condition for the disjoint set. The disjoint union of a set is also called discriminated union as well.
