c - Insert "E" after "T" in a string w/o tempering with "T" -


the goal insert "e" after occurrences of letter "t"

but code below does:

soon character "t" detected...

it replaces "t" "t" inserts "e"

how can altered not replace "t" "t" because seems work.

instead can leave alone existing "t" in place.. move after , insert "e".

char s1[1024]; int i, n;    (i=0, n = 0; s[i]!= '\0'; i++)   {     if (s[i] == 't')     {             s1[n] = 't';             n++;             s1[n] = 'e';             n++;     }     else     {         s1[n] = s[i];         n++;     } } s1[n] = '\0';

just copy characters , when see have copied t, copy e

s1[n] = s[i]; n++;     if (s[i] == 't') {   s1[n] = 'e';   n++; }

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
