What will be the output of the following code C?

#include <stdio.h>

 void solve(){

char ch[5] = "abcde";

int ans 0;

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

ans += (ch[i] - 'a');

}

printf("%d", ans);

}

int main(){

solve();

return 0;

}

What is the out come of the following Arduino code?

void setup(){

Serial.begin(9600);

}

void setup0{

Serial.write(20);

}

Predict the output of the following code if the object is moving away from the sensor

int op = 7;

int isBarrier = HIGH;

void setup() {

pinMode(op, INPUT)

Serial.begin(9600);

}

void loop() {

isBarrier = digitalRead(op);

if (isBarrier == LOW)

Serial.println("1+");

else{

Serial.print("clear+");

}

delay(100);

}

What will be the output of the following code

#include <stdio.h>

void solve0{

int b 4;

 int res = b++ + ++b + ++b

printf("%d"', res);

}

int main(){

solve();

 return 0;

}
