I am using system function to decrypt an encrypted file, But it's taking too much of time, as a result of file access
i want to know how to store the output of system( ) function into local variables instead of a file.
Code goes like this.
sprintf(syscommand,"des -D -k %c%c credit0_e credit0",keys,keys[j]);
my professor gave an hint saying we can use pipes(|) to redirect output to local variables. I don't know how to do that please help me
