Answer #include<stdio.h>
int main(){
int num,i,count,min,max;
printf("Enter min range: ");
scanf("%d",&min);
printf("Enter max range: ");
scanf("%d",&max);
for(num = min;num<=max;num++){
count = 0;
for(i=2;i<=num/2;i++){
if(num%i==0){
count++;
break;
}
}
if(count==0 && num!= 1)
printf("%d ",num);
}
return 0;
}
Alternate with while loop#include<stdio.h>
int main(){
int num,i,count,min,max;
printf("Enter min range: ");
scanf("%d",&min);
printf("Enter max range: ");
scanf("%d",&max);
num = min;
while(num<=max){
count = 0;
i=2;
while(i<=num/2){
if(num%i==0){
count++;
break;
}
i++;
}
if(count==0 && num!= 1)
printf("%d ",num);
num++;
}
return 0;
}
Sample output:
Enter min range: 10
Enter max range: 50
