How to store a data of a structure into a text file.

I have created a structure in which 4 variables are defined. How to store the values of structure into a text file.

Answer 1

[Geoff Hayes]

Priyanka - if you just want to write the structure to file, then just try using fopen to open the file, fprintf to write the data (each of the four variables) to file, and fclose to close the file.

s1.name = 'fred';
s1.age = 42;
s1.height = 170;
s1(2).name = 'alice';
s1(2).age = 29;
s1(2).height = 160;
fileID = fopen('use of structure .txt','a');
    fprintf(fileID, 'Missile #         :%s \n', s1.name);
    fprintf(fileID, 'Operator Name     :%s \n', s1.age);
    fprintf(fileID, 'Operator Name     :%s \n', s1.height);
    fprintf(fileID, 'Missile Type      :%s \n', s1(2).name);
    fprintf(fileID, 'Missile ID        :%s \n',s1(2).age);
    fprintf(fileID, 'Container Number  :%s \n', s1(2).height);
 
 fclose(fileID);

simply fprintf is not write structure variable in text file

Error occur ''Scalar structure required for this assignment.

Error in Untitled (line 36)

s1.name = 'fred';''
