Question: ques a consider the two variables below char amessage ...

QUES)

a)

Consider the two variables below.

char amessage[] = "now is the time";

char *pmessage = "now is the time";

I. What is the difference between the two variables amessage and pmessage?

II. Write a C code to change the character ‘t’ from ‘time’ to uppercase ‘T’ in the variable

amessage.

b)

Consider the following code.

void strcopy(char s1[ ], char s2[ ])

{

int len = strlen(s2);

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

s1[i] = s2[i];

}

}

int main () {

char s2[10] = "copy this";

char s1[10];

strcopy(s1, s2);

}

The above code copies the character from s2 to s1 using the concept of array, in the strcopy function.

Implement another function strcopy2 that achieves the same result, but that takes as input pointers

to character arrays – that is, complete the strcopy2 function in the following code so that the code

copies the content of s2 into s1.

void strcopy2(char *s1, char *s2) {

}

int main () {

char s2[10] = "copy this";

char s1[10];

strcopy2(s1, s2);

}
