Hello, for my online class I should write a a line wich displays the Percentage of the Earth Layers. I choose the fprintf command and set the calculatet Percentage in it.

fprintf('\nPercentage of the EarthLayer:\nCore:   %.1f%%\nMantle: %.1f%%\nCrust:   %.1f%%\n\n',PercentCore,PercentMantle,PercentCrust)

Now I would like to save this as a .txt file. But when i type "save" and try to save it, it just saves a .txt file with the Number 74, I really don't get what i'm doing wrong...

Can anybody help me?

You can refer to fprintf documentation, it's Examples & fileID = fopen(filename,permission)

fileID = fopen('textFile.txt','w');
fprintf(fileID,'\nPercentage of the EarthLayer:\nCore:   %.1f%%\nMantle: %.1f%%\nCrust:   %.1f%%\n\n',PercentCore,PercentMantle,PercentCrust);
fclose(fileID);
