I need to know how to access the first position of the vector of pointers * c_parte_real, as shown below:
typedef struct{
struct char_vector{
char *c_parte_real[2], *c_parte_imag[2];
}c_vector;
struct int_vector{
int *i_parte_real[2], *i_parte_imag[2];
}i_vector;
struct complex_num{
float real1,real2,imag1,imag2;
}comp_num;
}expressao_complexa;
I made a simplified to make it clearer, I created a variable to receive the position value
#include "stdio.h"
int main(void) {
typedef struct char_vector{
char *c_parte_real[2], *c_parte_imag[2];
}c_vector;
char a,b;//variável que recebe o valor
c_vector x;
x.c_parte_real[0]='2';
a = x.c_parte_real[0];
x.c_parte_real[1]='3';
b = x.c_parte_real[1];
printf("a=%c\n",a);//imprime na tela
printf("b=%c\n",b);//imprime na tela
return 0;
}
test no: link
x , of type expressao_complexa , access can be done directly:
...
expressao_complexa x;
// atribui um valor
x.c_vector.c_parte_real[0] = "1.0";
// imprime o valor atribuído
printf("%s\n", x.c_vector.c_parte_real[0]);
...
The above answers are correct, but, your code is wrong, you can not declare structures within structure declarations. What you can do is have structures as components of structure declarations.
