See Java regex Documentation

If you want to do a split (and the purpose is to obtain only digit characters), use regular expression that splits at any non-digit character (i.e. "[^\d]+"). Then you would get an array containing only digit characters.

If you are dealing with mathematic expressions, spliting a string into a char array would be OK because you will need to deal with the whole string (numbers & operands).

#include<stdio.h> #include<conio.h> typedef struct process{ char pname[20]; int at,bt,wt,ta,end; }processes; int main(){ processes P[10]; processes z[10]; processes et[10]; processes wt1[10]; processes ta1[10]; int a,b,n,x=0,st,y,w; float aveta,avewt,sumta=0,sumwt=0; printf("Process Scheduling Algorithm:\n"); printf("SHORTEST ...
