Question

Write the equivalent code, using a while loop for the following code.

for (j = 0; j < 20; j = j + 1)
printf("j is %d\n", j);

Answer 1

int j = 0;
while(j<20){
printf("j is %d\n",j);
j++;
}

Answer 2

In general, a for loop has:
```
for (initial_statement; condition; step_statement) {
loop_statements;
}

```
This can be reorganized into
```
initial_statement;
while (condition) {
loop_statements;
step_statement;
}
```
