seria legal um exemplo mais complexo do uso algo como
#include <stdio.h>
#include <stdlib.h>
int main(void){
int dia, mes, ano;
char *source = (char *) malloc(100 * sizeof(char));
char *target = (char *) malloc(100 * sizeof(char));
source = "27/05/2001";
sscanf(source, "%d/%d/%d", &dia, &mes, &ano);
printf("source: %s\n", source);
sprintf(target, "-> %d-%d-%d", dia, mes, ano);
printf("target: %s\n", target);
}n adicionei comentários, é só uma possibilidade 🤯

| // Caso o sscanf não tivesse sido usado, teriamos que programar o código para passar por cada casa do vetor variavel2, |

acho que esse comentário pode confundir iniciantes, o uso das funções atoi, atof e etc conseguem converter
Correções e melhorias após revisão, visando melhor entendimento do leitor, sobre as variações do printf e scanf
