 <![endif]-->  Nesta aula começamos a estudar vetores, o professor Jossandro nos passou algumas explicações e seguimos fazendo alguns exercícios, segue abaixo o conteúdo apresentado em aula.





1 - Faça um programa que leia 10 nomes de alunos, guarde em uma lista e mostre.

algoritmo "nome_alunos"
var
&nbsp;&nbsp; nomes: vetor[1..10] de caractere
&nbsp;&nbsp; i: inteiro
inicio
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval ("Informe o nome ",i," :")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(nomes[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval ("O nome ",i," e ", nomes[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara

2 - Faça um programa que leia 10 nomes de alunos e sua media final e guarde em listas. Ao final listar o nome dos alunos e sua media, mostrando "aprovado" se a media for maior ou igual a 7 ou "reprovado" caso contrario.

algoritmo "nomes_media"
var
&nbsp;&nbsp; nomes: vetor [1..10] de caracter
&nbsp;&nbsp; medias: vetor [1..10] de real
&nbsp;&nbsp; i: inteiro
inicio
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Informe o nome ",i,":")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(nomes[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Informe a media do aluno ",i,":")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(medias[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreva("Aluno(a) ",nomes[i]," tem media ",medias[i]," e esta ")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; se (medias[i]&gt;=7) entao
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("aprovado")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; senao
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("reprovado")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimse
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara

3 - Faça um programa que leia 50 valores reais e guarde em um vetor. Ao final mostrar a soma e a media dos valores lidos.

algoritmo "soma_media"
var
&nbsp;&nbsp; num: vetor[1..50] de real
&nbsp;&nbsp; i: inteiro
&nbsp;&nbsp; media, soma: real
inicio
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; soma&lt;- 0
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 50 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Informe um numero: ")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(num[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; soma&lt;- soma+num[i]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; FIMPARA
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; media&lt;- soma/50
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("A soma dos 50 numeros digitados e: ", soma)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("A media dos 50 numeros digitados e: ", media)
fimalgoritmo

4 - Faça um programa que calcule a media ((nota1+nota2)/2) de 10 alunos e guarde em um vetor, percorra o vetor e mostre as medias. Ao final mostre a media geral do turno.

algoritmo "media_geral"
var
&nbsp;&nbsp; medias: vetor [1..10] de real
&nbsp;&nbsp; i: inteiro
&nbsp;&nbsp; media_tot, nota1, nota2, geral: real
inicio
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Digite a primeira nota do aluno ",i," :")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(nota1)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Digite a segunda nota do aluno ",i," :")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(nota2)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; medias[i]&lt;- ((nota1+nota2)/2)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; limpatela
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; geral&lt;-0
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; para i de 1 ate 10 faca
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("A media do aluno(a) ",i," e: ",medias[i])
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; geral&lt;- geral+medias[i]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fimpara
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; media_tot&lt;- geral/50
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("A media do turno e: ", media_tot)

5 - Faça um programa que mostre o mês dos ano de acordo com o numero (de 1 a 12) informado pelo usuário.

algoritmo "mes"
var
&nbsp;&nbsp; mes: vetor[1..12] de caractere
&nbsp;&nbsp; num: inteiro
inicio
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[1]&lt;- "Janeiro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[2]&lt;- "Fevereiro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[3]&lt;- "Março"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[4]&lt;- "Abril"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[5]&lt;- "Maio"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[6]&lt;- "Junho"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[7]&lt;- "Julho"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[8]&lt;- "Agosto"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[9]&lt;- "Setembro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[10]&lt;- "Outubro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[11]&lt;- "Novembro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; mes[12]&lt;- "Dezembro"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; repita
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("Digite o numero equivalente ao mês desejado: ")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; leia(num)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ate (num&gt;=1) e (num &lt;=12)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; escreval("O mês digitado e: ", mes[num])

Algumas duvidas surgiram ao decorrer dos exercícios, mais consegui entender o conteúdo sem problemas. Agora percebe-se que já avançamos bastante na disciplina.
