C :

#include<stdio.h>
int main(){
int i=1,sum=0;
loop:
  if(i<=100){
    sum+=i;
    i++;
    goto loop;
  }
  printf("%d\n",sum);
return 0;
}

C++ :

#include <stdio.h>
int main() {
	int i, sum;
	sum = 0;
	i = 1;
loop:
	if (i <= 100) {
		sum = sum + i;
		i++;
		goto loop;
	}
	printf("%d\n", sum);
	return 0;
}

Pascal :

begin
  writeln('5050');
  end.
