As homework, I must swap letters in a given string. I already figured out how to do this, but not how to display them at once. it involves a for loop. so if I include disp x in the for loop, it displays them between parentheses and a space, but I want them all together, so instead of
"a"
"b"
"c"
I want "abc". Is there a way to do this? Should I push the variable into an array and then display the array after the for loop? How to push variables in to an array?
This is in TI-Nspire CX Cas btw.
To add an element x to an array A use augment(A, {x}).
For your specific case, I would use a string variable (call it string) to which I concatenate the next letter at each iteration of the for loop. So if the next letter to be added is in the variable letter, you would put the following line of code at the end of your for loop: string := string & letter.
