Coroutines in C/C++
In this tutorial, we will be discussing a program to understand coroutines in C/C++.
Coroutines are control instructions which switch the execution control between two routines which returning any of them.
Example
#include<stdio.h>
int range(int a, int b){
static long long int i;
static int state = 0;
switch (state){
case 0:
state = 1;
for (i = a; i < b; i++){
return i;
//returning control
case 1:; //resuming control
}
}
state = 0;
return 0;
}
int main(){
int i;
for (; i=range(1, 5);)
printf("control at main :%d\n", i);
return 0;
}Output
control at main :1 control at main :2 control at main :3 control at main :4
