Bash Shell Scripting - Dialog form variables -


so, took shell scripting , i'm developing address book.

for user insert contact made form:

form=$(dialog                                      \     --title "inserir"                              \     --form  ""                                     \     0 0 0                                          \     "nome:"      1 1    "$nome"     1 10 20 0      \     "morada:"    2 1    "$morada"   2 10 20 0      \     "telefone:"  3 1    "$telefone"     3 10 20 0  \     "e-mail:"    4 1    "$mail"     4 10 20 0      \   2>&1 1>&3)

and want insert values through mysql query. saw somewhere had use, instance:

form[$1]

in order access variable $nome. however, comment 2008. easiest way access variables?

thank you!

ifs=$'\n' read -r -d '' nome morada telefone mail < <( dialog ... )

unlike dialog ... | { read; ... } (which scopes variables read subshell), approach puts dialog in subshell, , variables in main shell -- more convenient.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
