Just use a for loop to go through the array and multiply the elements one at a time in an accumulator. The initial value of the accumulator is 1 because this is the neutral element of multiplication.

int array[] = {1,2,3,4};
int produto = 1, i;
for (i = 0; i < 4; i++) {
    produto *= array[i];
}

To multiply and sum the elements of an array is basically to make a succession of terms.

We have the following: //////////////////

int *vector = {1,2,3,4};
int i, total = 0;
/*Realizar a primeira iteracao da sucessao*/
total = vetor[0];
/*Fazer um ciclo a começar em i=1*/
for(i=1; i<4; i++){
   total = total * vetor[i];
}
printf("Total: %d", total);

Make a repeat loop by traversing the entire array, create an integer type variable to store the result, and multiply it by the value in the array index .....

int main(){
    int vetor[4] = {1,2,3,4};
    int total = vetor[0];
    total = vetor[0];
        for(int i=1; i<4; i++){
            total = total * vetor[i];
        }
    printf("%d", total);
}
