Answer - Identify errors in C program code, correct it and predict the output.

Answer: Corrected C program with Output.

Program-1

#include<stdio.h>

int main()

{

            char str1[10]="ABCDE", str2[10]="XYZAB";

            printf("String1:%c\n", str1[2+1]);

            printf("String2:%s\n", str2);

            printf("String1 = %d \n", strlen(str1));

            printf("String2 = %d \n", strlen(str2));

            return 0;

}

Output of the program:

String1:D

String2:XYZAB

String1 = 5

String2 = 5

Program-2

#include<stdio.h>

void main() {

            int i, max, marks[5]={5,2,3,6,8};

            max = marks[0];

            for(i=0; i<5; i++)

            {

                        if(marks[i] < marks[i+1])

                                    max = marks[i+1];

            }

            printf("Max marks = %d \n", max);

}

Output of the program:

Max marks = 8

Program-3

#include<stdio.h>

void main() {

            char name[10]="ABCEDFGH";    

            name[0] = 'A';    

            name[2] = 'H';

            name[0] = name[2];

            printf("%c %d", name[0], name[1]);   

}

Output of the program:

H 66
