could someone explain it to me how five_int[0] and five+ints[1] change during the for loop

#include

int main() {

int i;

int five_ints[5];

char* c;

for (i = 0; i < 5; i++){

five_ints[i] = 4;

}

c = (char*)five_ints;

for (i = 0; i < 5; i++){

c[i] = 1;

}

printf("%x ", five_ints[0]);

printf("%x ", five_ints[1]);

printf("%x ", five_ints[2]);

printf("%x ", five_ints[3]);

}
