How to create a cglm Mat4 from a float[16] array? - c

Question

I know C++ has glm::make_mat4() with #include <glm/gtc/type_ptr.hpp>, but there does not seem to be a make_mat4() function available in CGLM.
Can someone please tell me how to create a CGLM Mat4 from a float[16] array?
I tried the following, but the Mat4 does not seem to print the float values I'm expecting.
#include "cglm/cglm.h"
#include "cglm/call.h"
void main() {
// Atempt #1
float aaa[16] = {
1, 2, 3, 4,
5, 6, 7, 8,
9, 10, 11, 12,
13, 14, 15, 16
};
mat4 bbb = {
{ aaa[0],aaa[1],aaa[2],aaa[3] },
{ aaa[4],aaa[5],aaa[6],aaa[7] },
{ aaa[8],aaa[9],aaa[10],aaa[11] },
{ aaa[12],aaa[13],aaa[14],aaa[15] }
};
for (int i = 0; i < 4; i++) {
for (int k = 0; k < 4; k++) {
printf("%d", bbb[i][k]);
printf("\n");
}
}
printf("\n");
// Atempt #2
//void *memcpy(void *dest, const void * src, size_t n)
memcpy(bbb, aaa, sizeof(aaa));
for (int i = 0; i < 4; i++) {
for (int k = 0; k < 4; k++) {
printf("%d", bbb[i][k]);
printf("\n");
}
}
}

You need to make a void main() function as an entry point. Otherwise the compiler wont know where you program starts.
int main(){
float aaa[16] = {
1, 2, 3, 4,
5, 6, 7, 8,
9, 10, 11, 12,
13, 14, 15, 16
};
float bbb[4][4] = {
{ aaa[0],aaa[1],aaa[2],aaa[3] },
{ aaa[4],aaa[5],aaa[6],aaa[7] },
{ aaa[8],aaa[9],aaa[10],aaa[11] },
{ aaa[12],aaa[13],aaa[14],aaa[15] }
};
for (int i = 0; i < 4; i++) {
for (int k = 0; k < 4; k++) {
printf("%f", bbb[i][k]);
printf("\n");
}
}
printf("\n");
}
This code works in for me.
The diffrence to your code is:
The main function
I changed the data type from the bbb array to float and used the dimensions 4 by 4
I used %f in the printf function for printing the values
