<Olá, alguém poderia me ajuda a questão é a seguinte tô criando um sistema bancário básico com interface grafica, para fim didático, tem uma janela com os comandos de login e cadastro e outra janela com já os sistema de depósito e saque e mostrador de saldo que são apenas áreas de textos e os botões a minha dificuldade no caso é na hora de fazer a transição de uma janela para outra quando o usuário pressiona botão de login fecha essa janela e abre as com os botões de depósito e saque, aí gostaria de saber alguém tem um exemplo de código ou algum site em que eu possa aprender Uso Windows.h win32 Quero aprender nesse primeiro antes de passa para sistemas que já me dá tudo mastigado como gtk.

Nao porque por me darem as raizes que sao exatas em decimal eu quero separado exato com resultado exato e os nao como sao, em decimais. Mais uma vez muito obrigado por me responder

Opa, obrigado por me responder bem essa parte do código que quando difere do zero ele faz outra equaçao para calcula a parte fracionaria dos que nao tem raiz exata. if(a==0){ return n; }else { int b= a*100; // b equivalente a * 100 int k = 0; // int c= (n*20)+1; // c é o n transformado em equivalente ao i while (b>=c){ b=b-c; c=c+2; k=k+1; } float e= k/(float)10; float d= n + e; printf("A Raiz Quadrada é %f\n", d); } } O código anterior quando nao tinha a chamada a funçao raiz me dava os calculos normais, só quando criei essa funcao fora do main vem os resultados em float e logo abaixo em inteiro só que nao era pra vim nada, e vem um numero nada ver.

Olá, bom dia sou um entusiasta em programação preciso de uma ajuda, sei que esse tópico tem já um tempo eu tenho um código que me da a raiz quadrada de um numero sendo ele raiz inteira ou decimais só que no resultado das decimais ele me da o decimal e um segundo resultado inteiro errada alguém pode me da um alo onde estou errando #include <stdio.h> #include <stdlib.h> int raiz (int a){ int n=0; /* Código extraido da equaçao de pell da qual permite encontrar a parte inteira de uma Raiz*/ int i=1; /* quadrada simplesmente subtraindo inteiros ímpares. Exemplo: Raiz de 19.*/ while(a>=i){ /* 1. 19 - 1 = 18 Como 3 é menor que 9 a sequencia para aqui*/ a=a-i; /* 2. 18 - 3 = 15 Como 4 subtrações foram efetuadas, entao a*/ i=i+2; /* 3. 15 - 5 = 10 resposta é 4.*/ n=n+1; /* 4. 10 - 7 = 3*/ } } if(a==0){ return n; }else { int b= a*100; // b equivalente a * 100 int k = 0; // int c= (n*20)+1; // c é o n transformado em equivalente ao i while (b>=c){ b=b-c; c=c+2; k=k+1; } float e= k/(float)10; float d= n + e; printf("A Raiz Quadrada é %f\n", d); } } int input( char mensagem[]) { int entrada; printf("%s",mensagem); scanf("%d",&entrada); return entrada; } int main(int argc, char *argv[]) { int valor; while (1) { valor = input("Digite o número para tirar raiz ou 0 para terminar"); if (!valor) break; printf("A Raiz quadrada é %d\n:", raiz(valor)); } return 0; }

Entendir obrigado

Valeu pela resposta, o 0 esqueci quando tava fazendo os botões kkk, é que eu gosto aprende bem do inicio mesmo porque tipo fazendo uma analogia nao tem como você aprender o funcionamento da construçao interna de circuito integrado sem você enteder primeiro de diodo e transistor de quais sao feitos os Cis, por isso prefiro mexer com essas nivell mais baixos, nao sei se to certo mais esses aqui que você cito me das as coisas mais mastigadas .
