C String Array MCQs

Predict the output of below program: #include <stdio.h> int main() { int arr[5]; // Assume that base address of arr is 2000 and size of integer // is 32 bit arr++; printf("%u", arr); return 0; }

• 2002
• 2004
• 2020
• Lvalue Error
• None

# include <stdio.h> void print(int arr[]) { int n = sizeof(arr)/sizeof(arr[0]); int i; for (i = 0; i < n; i++) printf(\"%d \", arr[i]); } int main() { int arr[] = {1, 2, 3, 4, 5, 6, 7, 8}; print(arr); return 0; }

• 1 2
• 1 2 3 4 5 6 7 8
• Compiler Error
• 1 2 3
• None

Predict output of following program int main() { int i; int arr[5] = {1}; for (i = 0; i < 5; i++) printf("%d ", arr[i]); return 0; }

• 1 0 0 0 0
• 1 1 1 1 1
• 1 Followed by garbage values
• 0 0 0 0 0
• Compiler Error

int main() { int i; int arr[5] = {0}; for (i = 0; i <= 5; i++) printf("%d ", arr[i]); return 0; }

• Compiler Error: Array index out of bound.
• The always prints 0 five times followed by garbage value
• The program always crashes
• The program may print 0 five times followed by garbage value, or may crash if address (arr+5) is invalid
• None

# include <stdio.h> int main() { char str1[] = "HelloWorld"; char str2[] = {'H', 'e', 'l', 'l', 'o', 'W', 'o', 'r', 'l','d'}; int n1 = sizeof(str1)/sizeof(str1[0]); int n2 = sizeof(str2)/sizeof(str2[0]); printf("n1 = %d, n2 = %d", n1, n2); return 0; }

• n1=11,n2=10
• n1=10,n2=11
• n1=9,n2=11
• n1=9,n2=10
• None

#include<stdio.h> int main() { char str[20] = "Helloworld"; printf ("%d", sizeof(str)); return 0; }

• 9
• 11
• 20
