Question

I want to ask how I can use %s to printf my string and scanf my string ?
how do I modify?
int main(void)
{
ASA_DEVICE_set();
int i;
int A[5][2];
char B[5][1];
int temp2=0, temp3=0,j=0;
char temp1;
for(int i=0; i<4;i++){
printf("key in your name :\n");
scanf("%s",&B[i][0]);}
for(int i=0; i<4;i++){
printf("key in your id :\n");
scanf("%d",&A[i][0]);}
for(int i=0; i<4;i++){
printf("key in your score :\n");
scanf("%d",&A[i][1]);
}
for(int k=0;k<4;k++) {
for( int j = k; j < 4; j++) {
if( A[j][1] < A[k][1] ) {
temp1 = B[j][0];
B[j][0] = B[k][0];
B[k][0] = temp1;
temp2 = A[j][1];
A[j][1] = A[k][1];
A[k][1] = temp2;
temp3 = A[j][0];
A[j][0] = A[k][0];
A[k][0] = temp3;
}
}
}
for(int i=0; i<5;i++){
printf("name:%s id:%d score:%d\n",B[i][0],A[i][0],A[i][1]);
}
}

Answer 1

Your printf / scanf logic is wrong as what you try to read / write is a character and not a string. Is it what you wanted to do ?
