C :

#include<stdio.h>
int main()
{
 int i=100;
 while((i%3==2 && i%5==3 && i%7==5)!=1) 
 i++;
 printf("%d",i);
}

C++ :

#include <iostream>
#include <iomanip>
using namespace std;

int main(){
    int i;
    for(i=100;i<=100000000;i++){
    	if(i%3==2&&i%5==3&&i%7==5){
    		cout<<i<<endl;
    		break;
		}
	}
}

Python :

s=100
while s<200:
    if s%3==2 and s%5==3 and s%7==5:       
        print(s)
    s+=1
