URI Online Judge | 1007

Difference

Adapted by Neilor Tonin, URI  Brazil
Timelimit: 1
Make a simple program that reads four variables named A, B, C and D. Calculate and print the difference of the product of A and B with the product of C and D (A * B - C * D).

Input

The input file contains 4 integer numbers.

Output

Print DIFERENCA (DIFFERENCE in portuguese) according to the following example, with a blank space before and after the equal signal.
Sample InputsSample Outputs
5
6
7
8		DIFERENCA = -26
0
0
7
8		DIFERENCA = -56
5
6
-7
8		DIFERENCA = 86
Solution:
#include<stdio.h>
int main(){
    int a,b,c,d;
    scanf("%d %d %d %d",&a,&b,&c,&d);
    printf("DIFERENCA = %d\n",((a*b)-(c*d)));
    return 0;

}

URI Online Judge | 1041 Coordinates of a Point (Solution)

Image
Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1041 URI Online Judge | 1041 Coordinates of a Point Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Write an algorithm that reads two floating values (x and y), which should represent the coordinates of a point in a plane. Next, determine which quadrant the point belongs, or if you are over one of the Cartesian axes or the origin (x = y = 0). If the point is at the origin, write the message "Origem". If the point is over X axis write "Eixo X", else if the point is over Y axis write "Eixo Y". Input The input contains the coordinates of a point. Output The output should display the quadrant in which the point is. Sample Input Sample Output 4.5 -2.2 Q4 0.1 0.1 Q1 0.0 0.0 Origem Solution: #include <stdio.h> int main() {      double x, y;      scanf ( "%lf %lf" , &x, &y);     ...

URI Online Judge | 1036 Bhaskara's Formula (Solution)

Image
Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1036 URI Online Judge | 1036 Bhaskara's Formula Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Read 3 floating-point numbers. After, print the roots of bhaskara’s formula. If was impossible to calculate the roots because a division by zero or a square root of a negative number, presents the message  “Impossivel calcular” . Input Read 3 floating-point numbers A, B and C. Output Print the result with 5 digits after the decimal point or the message if it is impossible to calculate. Sample Inputs Sample Outputs 10.0 20.1 5.1 R1 = -0.29788 R2 = -1.71212 0.0 20.0 5.0 Impossivel calcular 10.3 203.0 5.0 R1 = -0.02466 R2 = -19.68408 10.0 3.0 5.0 Impossivel calcular Solution: #include<stdio.h> #include<math.h> int main() {      double a,b,c,r1,r2,del;      scanf ( "%lf %lf %lf" ,&a,&b,&c);...

Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1043 URI Online Judge | 1043 Triangle Adapted by Neilor Tonin, URI   Brazil Timelimit: 1 Read three point floating values (A, B and C) and verify if is possible to make a triangle with them. If it is possible, calculate the perimeter of the triangle and print the message: Perimetro = XX.X If it is not possible, calculate the area of the trapezium which basis A and B and C as height, and print the message: Area = XX.X Input The input file has tree floating point numbers. Output Print the result with one digit after the decimal point. Sample Input Sample Output 6.0 4.0 2.0 Area = 10.0 6.0 4.0 2.1 Perimetro = 12.1 Solution: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #include <stdio.h> int main() {      double a,b,c;      scanf ( "%lf %lf %lf" ,&a,&b,&c...
