DOS is a single tasking operating system, thus only one program runs at a time. The Spawnl( ) function provides us with the capability of starting the execution of one program from within another program. The first program is called the parent process and the second program that gets called from within the first program is called a child process. Once the second program starts execution, the first is put on hold until the second program completes execution. The first program is then restarted. The following program demonstrates use of spawnl( ) function./* Mult.c */int main ( int argc, char* argv[ ] ){int a[3], i, ret ;if ( argc <> 3 ){printf ( "Too many or Too few arguments..." ) ;exit ( 0 ) ;}for ( i = 1 ; i < ret =" a[1]" val =" spawnl">
