URI ONLINE JUDGE SOLUTION 1040 - Average 3

Problem

Read four numbers (N1, N2, N3, N4), which one with 1 digit after the decimal point, corresponding to 4 scores obtained by a student. Calculate the average with weights 2, 3, 4 e 1 respectively, for these 4 scores and print the message "Media: " (Average), followed by the calculated result. If the average was 7.0 or more, print the message "Aluno aprovado." (Approved Student). If the average was less than 5.0, print the message: "Aluno reprovado." (Reproved Student). If the average was between 5.0 and 6.9, including these, the program must print the message "Aluno em exame." (In exam student).

In case of exam, read one more score. Print the message "Nota do exame: " (Exam score) followed by the typed score. Recalculate the average (sum the exam score with the previous calculated average and divide by 2) and print the message “Aluno aprovado.” (Approved student) in case of average 5.0 or more) or "Aluno reprovado." (Reproved student) in case of average 4.9 or less. For these 2 cases (approved or reproved after the exam) print the message "Media final: " (Final average) followed by the final average for this student in the last line.

Input

The input contains four floating point numbers that represent the students' grades.

Output


Print all the answers with one digit after the decimal point.

sample input output

Solution
#include<stdio.h>
int main()
{
    double N1,N2,N3,N4,N5,avr;
    scanf("%lf%lf%lf%lf",&N1,&N2,&N3,&N4);
    avr = ((N1*2)+(N2*3)+(N3*4)+(N4*1))/10.0;
    printf("Media: %0.1lf\n",avr);
    if(avr >= 7.0)
        printf("Aluno aprovado.\n");
    if(avr < 5.0)
        printf("Aluno reprovado.\n");
    if(avr >= 5.0 && avr<7.0){
        printf("Aluno em exame.\n");
        scanf("%lf",&N5);
        printf("Nota do exame: %0.1lf\n",N5);
        avr=(avr+N5)/2.0;
        if(avr >= 5.0)
            printf("Aluno aprovado.\n");
        if(avr<5.0)
            printf("Aluno reprovado.\n");
        printf("Media final: %0.1lf\n",avr);}
    return 0;

}

Solution Way:Here ,You have to find the average according with these number's given weights.At First we will take four double type variables.Then we will multiply each with it's weights.Then divide the total value with total weights. Then print some message as their requirements.In One condition you have to take another user input than repeat once. See my code for more understanding .Don't copy ,try yourself.

URI ONLINE JUDGE SOLUTION 1021 - Banknotes and Coins

Image
Problem Read a value of floating point with two decimal places. This represents a monetary value. After this, calculate the smallest possible number of notes and coins on which the value can be decomposed. The considered notes are of 100, 50, 20, 10, 5, 2. The possible coins are of 1, 0.50, 0.25, 0.10, 0.05 and 0.01. Print the message “NOTAS:” followed by the list of notes and the message “MOEDAS:” followed by the list of coins. Input The input file contains a value of floating point N (0 ≤ N ≤ 1000000.00). Output Print the minimum quantity of banknotes and coins necessary to change the initial value, as the given example. Solution #include<stdio.h> int main() {     int c[12],n,f,i,num[] = {100,50,20,10,5,2,100,50,25,10,5,1};     double x;     scanf("%lf",&x);     n = x;     f = x*100;     f = f%100;     printf("NOTAS:\n&q

URI ONLINE JUDGE SOLUTION 1036 - Bhaskara's Formula

Image
Problem Read 3 floating-point numbers. After, print the roots of bhaskara’s formula. If it's 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. Solution #include<stdio.h> #include<math.h> int main() {     double A,B,C,d,r1,r2;     scanf("%lf%lf%lf",&A,&B,&C);     d = B*B-4*A*C;     if(A != 0 && d>=0)     {         d = sqrt(d);         r1 = (d-B)/(2*A);         r2 = (-d-B)/(2*A);         printf("R1 = %0.5lf\nR2 = %0.5lf\n",r1,r2);     }     else printf("Impossivel calcular\n");     return 0; } Description: Here the problem is about a mathematical equation. We already know a equation ax^2 + bx + c=0 .You have to find the roots of
