0 == Douplus == Posted June 23, 2004 Report Share Posted June 23, 2004 Olá,Bom, não é nada muito grave, na verdade são erros comuns de programação (eu acho), você só esqueceu alguns ponto-e-vírgula( ; ) e esqueceu de fechar um bloco.Eu dei uma arrumada, compilei no meu Dev-C++ e funcionou. Veja: /* 115829,96,2004/06/23 19:31:29,1354 */ #include <stdio.h> int main (void) { char c; double v1 , v2; double a; char linha[121]; FILE* ent=fopen("entrada.txt", "wt"); FILE* sai=fopen("saida.txt", "wt"); if ((ent==NULL) || (sai==NULL)) { printf("problemas com os arquivos\n"); return 0; } while (fgets(linha,121,ent)) { int n = sscanf(linha," %c %lf %lf ",&c,&v1,&v2); if (n>0) { switch(c){ case '#': continue; break; case 'T': if (n!=3){ printf("ERRO\n"); } else{ a=(v1*v2)/2; printf("%f\n", a); fprintf(sai,"%c %lf",c,a); } break; case 'R': if (n!=3){ printf("ERRO\n"); } else { a=(v1*v2); printf("%lf\n", a); fprintf(sai,"%c %lf",c,a); } break; case 'C': if (n!=2){ printf("ERRO\n"); } else { a=3.14*(v1*v1); printf("%lf\n", a); fprintf(sai,"%c %lf",c,a); } break; default: printf("ERRO\n"); break; } fclose(ent); fclose(sai); return 0; } } } Quote Link to comment Share on other sites More sharing options...
