EXERCICIO DE ALGORITMICO – AULA 9

EXERCICIO DE ALGORITMICO – AULA 9

1.	Qual das opções abaixo está correta com relação a declaração de variáveis para um vetor de 15 elementos de números reais em C++?

		int vetor[15][15]
		double x[15]
		int vetor[15]
		double x[15][15]
		char x[15]

2.	Para que possamos construir um programa em C++ que "armazene sexo e idade de 5 pessoas, exiba uma listagem contendo sexo e idade de todas as pessoas e, ao final, o total de pessoas do sexo masculino e a soma das idades" podemos utilizar:  I. Dois vetores: um do tipo char para armazenar os sexos e o outro do tipo int para armazenar as idades.  II. Dois acumuladores (duas variáveis) também do tipo char: um para contar as pessoas do sexo masculino e outro para somar as idades. III. Duas estruturas de repetição (uma para entrada e outra para saída). Analise as senteças e marque a resposta correta.

		Somente a sentença III está correta
		Somente as sentenças I e III estão corretas
		Somente as sentenças I e II estão corretas
		Somente as sentenças II e III estão corretas
		Todas as sentenças estão corretas

3.	Analise as sentenças abaixo sobre a declaração de vetores e, em seguida, assinale a alternativa correta:  I. Na linguagem C++, uma string é um vetor de caracteres terminado com um caracter nulo cujo valor inteiro é igual a zero (código ASCII igual a 0).  II. O terminador nulo também pode ser escrito usando a convenção de barra invertida do C++ como sendo '\0'.  III. Como precisamos reservar duas posições para o terminador (a barra e o zero), sempre iremos declarar o tamanho necessário menos um.

		Todas as sentenças estão corretas
		Somente as sentenças I e III estão corretas
		Somente as sentenças II e III estão corretas
		Somente as sentenças I e II estão corretas
		Somente a sentença II está correta

4.	<a[i]<<" body="" <="" dos="" exibição="" a="" produz="" questão="" em="" código="" de="" trecho="" o="" que="" dizer="" pode-se="" ?;=""> Podemos dizer que uma matriz é um conjunto de variáveis, todas com o mesmo nome e só diferenciadas pela posição que ocupam nesse conjunto. Seja o vetor A, declarado e inicializado como:    int A[]={1,2,3,4,5,6,7,8,9,10}; Considere o seguinte trecho de código:    for(int i=0;i < 10; i++ )        if(  !(A[i]%2) )cout << A[i] <<" "; <a[i]< Pode-se dizer que o trecho de código em questão produz a exibição dos : </a[i]<</a[i]<<">

		a) elementos pares do vetor A.
		c) todos os elementos do vetor A.
		b) elementos ímpares do vetor A.
		e) Nenhum elemento do vetor A.
		d) todos os elementos menores que 10 do vetor A.

5.	Um lojista gostaria de desenvolver um programa para armazenar os códigos(valores inteiros), os valores de compra(valores reais), os valores de vendas(valores reais) e a quantidade(valores inteiros) de todos os mil produtos.  Pensou em declarar algumas matrizes unidimensionais para tornar isso possível.  Qual das opções abaixo declara as matrizes necessárias para que o programa possa ser desenvolvido a partir delas e seguindo, rigorosamente, as sugestões do texto acima?

		int codigos[999], qtdade[999]; float valorC[999], valorV[999];
		double codigos[999], qtdade[999], valorC[999], valorV[999];
		double codigos[1000], qtdade[1000], valorC[1000], valorV[1000];
		double codigos[1000], qtdade[1000]; float valorC[1000], valorV[1000];
		int codigos[1000], qtdade[1000]; float valorC[1000], valorV[1000];

6.	Os chamados vetores e matrizes podem ser considerados como:

		Comandos de seleção composta
		Comandos de seleção
		Estruturas de dados homogêneas
		Estruturas de dados heterogêneas
		Comandos de repetição
